Aeromexico Seat Upgrade Guide: Business Class, Premier Class and Upgrade Costs

There's a particular kind of satisfaction that comes from settling into a wider seat, accepting a pre-departure drink, and watching economy passengers file past on their way to the back. For passengers booked on Aeromexico, that experience — whether in the AM Plus cabin or in the full Clase Premier business class — is more accessible than many people realize. The airline offers multiple legitimate paths to an Aeromexico seat upgrade, and knowing how each one works helps you choose the option that fits your budget, your timeline, and your Club Premier status.

This guide covers every upgrade method Aeromexico offers: paid upgrades, bid upgrades, miles-based upgrades, and same-day options at the airport. It explains the Aeromexico seat upgrade policy in plain terms, breaks down the benefits you actually gain by moving up, and gives you the real picture on what each path costs — so you can make the decision that works for you rather than guessing.

Understanding Aeromexico's Cabin Structure Before You Upgrade

Before deciding which upgrade to pursue, it helps to understand exactly what you're upgrading into. Aeromexico operates three distinct service tiers, and the differences between them are significant enough that not every upgrade makes the same sense for every passenger.

Basic Economy (Tarifa Basic) The entry-level fare on Aeromexico comes with the fewest benefits and the most restrictions. Basic economy passengers have limited or no access to seat selection before check-in, are not eligible for upgrades after ticketing under the standard upgrade policy, and pay higher fees for any changes. If you're looking to upgrade an Aeromexico seat, this is the one fare type that creates the most limitations.

Classic Economy Standard economy on Aeromexico. Classic fares include seat selection, one carry-on plus a personal item, and are generally eligible for upgrade through paid, bid, or miles-based methods. This is the fare type most upgrade paths are built around.

AM Plus AM Plus is Aeromexico's premium economy product, occupying the rows immediately behind Clase Premier. It offers extra legroom (typically 34–36 inches of seat pitch depending on the aircraft), Sky Priority benefits including dedicated check-in, priority boarding, and priority baggage claim, and one checked bag included. AM Plus is a meaningful upgrade from Classic economy, particularly on routes of 2–4 hours where lie-flat seats aren't the priority.

Clase Premier (Business Class) Clase Premier is Aeromexico's full business class cabin. On short-haul and domestic routes, it features recliner-style seats with significantly more space and meal service. On long-haul routes — particularly on Boeing 787 Dreamliner aircraft — Clase Premier becomes Premier One, offering fully lie-flat seats, direct aisle access for all passengers, an onboard bar area called the Espacio Premier, and a more comprehensive dining service. Clase Premier is the primary destination for most Aeromexico business class upgrade paths.

You're Booking Right Now and Want to Start in a Better Seat: Upgrading at the Time of Purchase

The cleanest, most straightforward Aeromexico seat upgrade happens at the point of booking. When searching for flights on aeromexico.com or through the Aeromexico app, the fare selection screen displays the different cabin options side by side — Basic, Classic, AM Plus, and Clase Premier — with their respective prices.

Buying up at the time of booking is the most reliable way to secure both the cabin and a specific seat, since Clase Premier seats fill from the front and the best positions (window seats, bulkhead rows, and specific Premier One seats on Dreamliners) go early. If you have a preferred seat type — an aisle seat for easy lavatory access on a red-eye, for example, or a window seat on the Dreamliner for the extra privacy — booking directly into Clase Premier is the only way to guarantee it.

The Aeromexico upgrade cost at booking is essentially the fare difference between the economy cabin and the Premier cabin for that specific route and departure date. Aeromexico uses dynamic pricing, which means this number shifts based on demand, how far in advance you're booking, and what promotional fares are active. As a general reference point, domestic Mexico Clase Premier fares are often surprisingly affordable relative to economy on the same route — sometimes only $50–$150 more for short sectors. International routes to the US and longer segments carry more significant fare differences.

Booking tip: If you're debating between AM Plus and Clase Premier on a 2-hour domestic segment, the key differentiator is the Salón Premier lounge access before your flight. On a same-day business trip from Mexico City to Guadalajara and back, lounge access at AICM alone can justify the jump to Clase Premier if you have a long wait between meetings and a return flight.

You Already Have a Booking and Want to Move Up: How to Upgrade Aeromexico Flight After Booking

Booking a ticket and then wanting a better seat later is one of the most common upgrade situations — and Aeromexico accommodates it through multiple channels.

Via My Trips Online The primary path for passengers who want to upgrade Aeromexico flight after booking is through the My Trips portal on aeromexico.com.

1. Go to aeromexico.com and click "My Trips"
2. Enter your confirmation number and last name
3. Once inside your booking, navigate to "Personalize" or "Customize"
4. Select "Upgrade"
5. Choose the cabin you want to upgrade to — AM Plus or Clase Premier
6. Review the cost and available seats
7. Confirm with your payment method

The upgrade is processed immediately if seats are available, and you'll receive an updated confirmation email with your new cabin assignment. You can then use web check-in to select your specific Clase Premier seat, subject to availability.

By Phone If you'd prefer to speak with an agent — or if the online upgrade option isn't showing for your specific booking — the Aeromexico Call Center handles upgrade requests for existing bookings. Call 1-800-237-6639 from the US or 01-800-021-4000 from Mexico. Have your confirmation number ready.

Key restriction to know: Aeromexico paid seat upgrades are not available on codeshare flights operated by partner airlines. If your booking shows an Aeromexico flight number but the aircraft is actually operated by Delta or another SkyTeam partner, check with the operating carrier for upgrade options on that segment.

You Want to Pay Less Than the Full Fare Difference: How the Aeromexico Bid for Upgrade Works

One of the most interesting and often overlooked upgrade options Aeromexico offers is the bid upgrade — a system that allows eligible passengers to name their own price for a Clase Premier upgrade, rather than paying the full published fare difference.

Here is exactly how the Aeromexico bid for upgrade works:

Step 1: Watch for the invitation email Not all bookings are eligible for bid upgrades, and Aeromexico selects eligible passengers automatically. If your booking qualifies, you will receive an email invitation — typically sent a few days to a few weeks before departure — with a link to participate in the upgrade auction on aeromexico.com.

Step 2: Submit your bid Click the link in the email. You'll be directed to the upgrade opt-in page where you can enter the amount you're willing to pay for the upgrade. There is typically a minimum bid amount shown, and you can bid above that minimum. Think of it as naming your price for the cabin difference.

Step 3: Wait for the result Aeromexico reviews all bids before the flight and accepts or declines them based on availability and bid amounts. You are not charged if your bid is unsuccessful — the system only charges your card if your bid is accepted.

Step 4: Receive confirmation (or not) If accepted, you'll receive a confirmation email. At that point, you can select your Clase Premier seat through web check-in, subject to availability. If declined, you fly in your original cabin with no charge.

Important rules to understand before bidding:

The lounge access exclusion is worth emphasizing. Passengers who win a bid upgrade from an economy base fare do not receive access to the Salón Premier lounge, even though they'll be seated in Clase Premier for the flight. If lounge access is important to you, consider a direct paid upgrade or a miles-based upgrade instead, or verify this detail with Aeromexico when your bid is accepted.

Bid strategy example: A passenger has a Classic economy ticket on the Mexico City to New York JFK route, purchased for $380. They receive a bid invitation offering a minimum bid of $180. They've flown this route before and know the Clase Premier published upgrade price is typically around $450 more. They submit a bid of $210, reasoning that it's competitive but not the maximum. Three days before the flight, they receive a confirmation — the bid was accepted. They board in Clase Premier, enjoy the lie-flat seat and full meal service on the overnight flight, and paid effectively $590 for what would have been a $830+ Clase Premier booking. The strategy works when you're flexible on outcome and willing to fly economy if the bid fails.

You Have Club Premier Miles and Want to Use Them: Aeromexico Upgrade With Miles

For members of Aeromexico's Club Premier loyalty program, upgrading with miles is one of the most valuable redemption options available — and one that works differently from the bid or paid upgrade paths.

How to upgrade Aeromexico flight with miles:

1. Log in to your Club Premier account on aeromexico.com
2. Go to My Trips → Personalize → Upgrade
3. The system will display eligible flights and the miles required for an upgrade
4. Select the upgrade and confirm — miles are deducted from your account and the upgrade is processed

Alternatively, call the Club Premier customer service line if you prefer to handle it by phone or if the online upgrade option isn't available for your specific booking.

Miles required for an Aeromexico upgrade with miles depend on the route and fare class of your ticket. The Club Premier program uses a dynamic award system, meaning the number of miles required shifts based on demand and availability rather than following a fixed chart. As a general reference, upgrade redemptions for short domestic segments start from around 5,000 Club Premier points, while upgrades on international routes require significantly more. Check the current mileage cost for your specific route through the My Trips upgrade tool, which shows live pricing.

Key points about the miles upgrade:

One often-missed opportunity: if you're a member of a SkyTeam partner program — particularly Delta SkyMiles — you can sometimes find more favorable redemption rates for Aeromexico Clase Premier upgrades through the partner program than through Club Premier directly. Checking both programs before committing to a miles upgrade is worth the few extra minutes.

You're Traveling Tomorrow and Want to Try for a Better Seat: Aeromexico Last Minute Upgrade Options

Last-minute upgrades on Aeromexico fall into two distinct categories: upgrades made during online check-in and upgrades requested at the airport counter on the day of departure. Both are real possibilities, but they work differently and carry different levels of certainty.

During Online Check-In (Up to 72 Hours Before Departure)

Aeromexico's online check-in opens 72 hours before scheduled departure. During this window, the My Trips portal may display an upgrade option if Clase Premier seats are still available. This is effectively the same My Trips upgrade path described above, but accessed during the check-in phase rather than post-booking.

If the flight has available Clase Premier seats and your fare class is eligible, the upgrade price shown during check-in may reflect a discounted "last-minute" rate — particularly if Aeromexico is trying to fill premium cabin seats that would otherwise depart empty. Aeromexico last minute upgrade pricing is not guaranteed to be lower than earlier options, but it occasionally is.

At the Airport Counter on Departure Day: Aeromexico Upgrade at Check-In

For passengers who didn't complete online check-in or who want to try for an upgrade in person, the Aeromexico airport counter is the final opportunity. Arrive earlier than you normally would — not at the last minute — to have time for this conversation.

At the check-in counter, ask the agent whether Clase Premier or AM Plus seats are available and whether a same-day upgrade is an option. Aeromexico agents can process paid upgrades at the counter using a credit card, and on routes where Clase Premier has unsold seats close to departure, agents sometimes have discretion to offer reduced upgrade prices to fill the cabin.

Aeromexico Same Day Upgrade realities:

If your original flight causes you to miss a connecting Aeromexico segment, the situation at the counter becomes more urgent — it's worth knowing your rights in advance. Check out Aeromexico's missed connection policy so you're prepared if a tight itinerary doesn't go as planned.

Club Premier Elite Status and Complimentary Upgrades

For Club Premier Platinum and Titanium members, complimentary upgrades at the airport are a documented benefit — subject to availability. The higher your status, the earlier in the priority order your name appears for any open Clase Premier seats. If you're a high-status Club Premier member, always identify yourself at the check-in counter and ask about upgrade availability even if you haven't pre-requested one.

What You Actually Get When You Upgrade: Aeromexico Premier Class Benefits in Detail

Upgrading an Aeromexico seat is only worth it if the benefits justify the cost for your specific situation. Here's what Clase Premier and AM Plus actually deliver, based on official Aeromexico policy:

Clase Premier (Business Class) Benefits

For elderly travelers or those with limited mobility, the Sky Priority check-in and priority boarding that come with Clase Premier make a tangible difference. Though Aeromexico also offers dedicated mobility assistance for seniors regardless of cabin class, which is worth arranging in advance of your trip.

AM Plus Benefits

What Changes After a Bid Upgrade Specifically

Because the bid upgrade has different terms from a direct Clase Premier purchase, it's worth listing the distinctions clearly:

How to Get Upgraded on Aeromexico: Which Path Makes Sense for Your Situation

Not every upgrade method is right for every passenger. Here's a practical guide to matching your situation to the right approach:

I'm booking right now and want the best seat for a long-haul flight to Europe or South America → Book directly into Clase Premier at checkout. The lie-flat seat on a Dreamliner overnight is a meaningful difference from economy on a 10+ hour flight. Check both aeromexico.com and SkyTeam partner sites (Delta, Air France) for the best Clase Premier pricing before committing.

I've already booked economy and the flight is weeks away → Use My Trips → Personalize → Upgrade now. Early access gives you the best seat selection within Clase Premier if the upgrade is approved. If the price is too high, keep checking — paid upgrade pricing can shift as the departure date approaches.

I received a bid upgrade email and I'm flexible on the outcome → Submit a bid slightly above the minimum. If accepted, great. If not, you fly in your original seat. There's nothing to lose except a few minutes of your time. Don't overbid in a panic — wait, think about what the upgrade is genuinely worth to you, and submit that number.

I'm a Club Premier member with miles I want to use → Check the miles cost via My Trips first. If it seems reasonable for the route, use miles — especially if you're holding miles that aren't earning interest and you have a specific trip where comfort matters. On routes where the miles cost is disproportionately high relative to the paid upgrade price, the paid path may be better value.

My flight is tomorrow and I haven't upgraded yet → Check during online check-in for any available upgrade option. If nothing shows up, arrive at the Aeromexico counter 2.5–3 hours before departure, ask about same-day availability, and be flexible on what's offered. High-status Club Premier members should always identify their status at this stage.

I have a domestic Mexico flight and I'm wondering if Clase Premier is worth it → On domestic segments, the decision often comes down to lounge access and baggage allowance. If you're connecting through AICM and have a long wait, Salón Premier access alone can be the deciding factor. If it's a short direct hop with no layover, AM Plus is often the better value — extra legroom and Sky Priority without paying for the full business class experience.

Aeromexico Seat Upgrade Policy: The Rules Every Passenger Should Know

Before committing to any upgrade path, here are the core rules from Aeromexico's official upgrade policy that affect what's possible and what isn't:

Fare eligibility: Basic economy tickets are generally not eligible for upgrades after ticketing. Classic, AM Plus, and higher fare tiers have access to paid, bid, and miles-based upgrade paths.

Codeshare restriction: Aeromexico seat upgrades are not available on codeshare-operated flights. If your Aeromexico-marketed ticket is operated by a partner carrier, upgrade must be requested through the operating airline.

Seat guarantee: Aeromexico cannot guarantee a specific seat within Clase Premier for upgrade passengers — seat assignment is subject to availability at the time of upgrade confirmation. To maximize your chances of a preferred seat, confirm your upgrade as early as possible and use web check-in immediately after confirmation.

Miles accrual after upgrade: Whether you upgrade via bid or miles, Club Premier members earn kilometers based on the original economy fare class — not the Clase Premier class. This is a significant policy point for status-chasers: an upgrade does not count toward Premier status earning at the Clase Premier rate.

Cancellation and refunds: Bid upgrade amounts are non-refundable and non-endorsable once confirmed. Paid upgrades through My Trips follow the cancellation terms of the original ticket's fare class. If you cancel a trip where you've paid for an upgrade, review the fare rules carefully — the upgrade portion may or may not be refundable depending on the original fare. Similarly, if there's a discrepancy in the passenger name on your booking, resolving it before upgrade confirmation is important — name correction fees may apply depending on the type of change needed. Learn more about the Aeromexico Airlines name change policy and how it works.

Upgrade availability: Aeromexico processes upgrades on a first-come, first-served and status-priority basis depending on the upgrade type. On popular routes and peak travel periods, Clase Premier inventory fills early — both for outright purchase and for upgrade eligibility. Acting early is almost always better than waiting.

Aeromexico Premium Economy Upgrade: Understanding AM Plus as a Middle Ground

Aeromexico does not operate a separately branded "premium economy" cabin in the traditional sense that some carriers do (such as Air France or British Airways). The AM Plus product fills this middle-ground role — it is positioned between Classic economy and Clase Premier in price and in the experience it delivers.

When passengers search for an Aeromexico premium economy upgrade, AM Plus is the product they'll find. It offers:

• Front-of-economy-cabin seating with extra legroom
• Sky Priority services (check-in, boarding, baggage)
• One checked bag included (on routes where economy pays)
• Priority baggage delivery at arrival

What AM Plus does not offer: lounge access, lie-flat seats, or the full Clase Premier meal service. It is a genuine comfort improvement over Classic economy, particularly for passengers who prioritize a faster airport experience and more leg space on 2–4 hour flights, without paying for the full premium cabin.

The AM Plus upgrade cost from Classic economy, when purchased through My Trips after booking, is typically a fraction of the Clase Premier upgrade price for the same route. On a domestic Mexico segment, the difference can be as little as $30–$60.

Final Word

Every upgrade method Aeromexico offers — direct purchase, My Trips post-booking, bid, miles, or airport counter — is a legitimate path to a better seat. The difference between passengers who consistently fly in Clase Premier at a price they're comfortable with and those who pay full business class fares every time isn't luck. It's knowing which tools exist and using them intentionally.

Bid when you're flexible on the outcome. Use miles when you have them and the route makes sense. Buy directly when you need the lounge and a guaranteed seat choice. Ask at the counter when it's a last-minute situation and you have nothing to lose.

Families traveling with infants should also factor in Aeromexico infant policy when planning an upgrade — lap infant arrangements and bassinet seat availability vary by cabin and aircraft type, so confirming these details ahead of time ensures the upgrade truly works for everyone in your group. The Aeromexico seat upgrade policy rewards passengers who plan ahead — earlier requests have better seat access, better pricing on direct purchases, and more time to course-correct if availability is limited. Whatever your next Aeromexico trip looks like, the upgrade is usually closer than you think.
