Aeroméxico check-in: cutoffs, carry-on rules, and bag fees
Check in online 48 hours before departure (domestic Mexico); 24 hours before departure (international, Basic fare) or 48 hours (Classic/AM Plus/Premier fares) and be through airport check-in by Aeroméxico's cutoff of 60 minutes before departure on domestic flights. Bag-drop closes 90 minutes before departure — miss that window and your bag may not make the plane even if you do.

When does Aeroméxico open online check-in?
Aeroméxico opens online check-in 48 hours before departure (domestic Mexico); 24 hours before departure (international, Basic fare) or 48 hours (Classic/AM Plus/Premier fares) and closes it 2 hours before departure. The moment the window opens today, check in — you lock in your seat, skip the ticket-counter queue, and have your boarding pass on your phone before you leave home.
What is Aeroméxico's airport check-in cutoff?
| Flight type | Check-in closes | Bag drop closes |
|---|---|---|
| Domestic | 60 minutes before departure | 90 minutes before departure |
| International | 90 minutes before departure | 3 hours before departure |
These are hard deadlines — Aeroméxico can give your seat to a standby traveler once the cutoff passes. Arrive with room to breathe, not at the last second.
Can I bring a carry-on on Aeroméxico?
Yes. One full-size carry-on and one personal item are included on main-cabin fares at no extra charge. The carry-on must fit in the overhead bin — Aeroméxico sets the limit at 55 x 40 x 25 cm (21.6 x 15.7 x 9.8 in), max 10 to 15 kg depending on fare.
Your personal item must fit under the seat in front of you (45 x 35 x 20 cm, max 3 kg (recommendation; must fit under seat)). Pack it smart so you have easy access during the flight.
How much does Aeroméxico charge for checked bags?
| Bag | Main cabin | Basic economy |
|---|---|---|
| 1st checked bag | $70 (low season) to $80 (high season) USD for US/Canada routes on Classic/Flex fares (no checked bag included); AM Plus Classic/Flex includes 1 bag | $30 USD for US/Canada on Basic fare (online pre-purchase); standard/at-airport rates are $70 to $80 USD — verify at booking |
| 2nd checked bag | $80 (low season) to $95 (high season) USD for US/Canada routes | $80 (low season) to $95 (high season) USD for US/Canada routes |
Prices shown are for online prepayment. Paying at the airport or the gate runs higher. Baggage fees compared across every airline shows how Aeroméxico stacks up against the rest.
How does a bag fee change my Leave-By Time?
Checking a bag adds 5 to 10 minutes at the counter — time in line, handing off the bag, collecting a receipt. That window sits between your arrival at the terminal and your walk to security, so it shifts your Leave-By Time at home earlier, not just your airport arrival.
Recompute your Leave-By Time with bag drop factored in — enter your flight, mark that you are checking a bag, and the calculator adds the counter time so you leave home with exact numbers, not a guess.
