Alaska Airlines check-in: cutoffs, carry-on rules, and bag fees
Check in online 24 hours before departure and be through airport check-in by Alaska Airlines's cutoff of 50 minutes before departure on domestic flights. Bag-drop closes 50 minutes before departure — miss that window and your bag may not make the plane even if you do.

When does Alaska Airlines open online check-in?
Alaska Airlines opens online check-in 24 hours before departure and closes it 50 minutes before departure (domestic); 60 minutes before departure (international). 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 Alaska Airlines's airport check-in cutoff?
| Flight type | Check-in closes | Bag drop closes |
|---|---|---|
| Domestic | 50 minutes before departure | 50 minutes before departure |
| International | 60 minutes before departure (90 minutes from Guadalajara) | 60 minutes before departure |
These are hard deadlines — Alaska Airlines 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 Alaska Airlines?
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 — Alaska Airlines sets the limit at 22 x 14 x 9 in (45 linear in, including wheels and handle).
Your personal item must fit under the seat in front of you (Not officially specified; must be a small item (purse, briefcase, or laptop bag) that fits under the seat). Pack it smart so you have easy access during the flight.
How much does Alaska Airlines charge for checked bags?
| Bag | Main cabin | Basic economy |
|---|---|---|
| 1st checked bag | $45 | $45 (Saver fare has same baggage fees as Main Cabin) |
| 2nd checked bag | $55 | $55 |
Prices shown are for online prepayment. Paying at the airport or the gate runs higher. Baggage fees compared across every airline shows how Alaska Airlines 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.
Things to know before you fly Alaska Airlines
- Saver fare (lowest tier) includes a free full-size carry-on bag unlike most airlines' basic economy — same carry-on and checked bag fees as Main Cabin; however, Saver passengers board last (Group F) so overhead bin space is first-come, first-served.
- Baggage fee increase effective April 10, 2026: first checked bag rose to $45 (from $40) and second to $55 (from $45) for North America flights ticketed on or after that date.
- Atmos Rewards Visa cardholders and Atmos Silver+ elite members receive 1+ free checked bags; First Class passengers receive 2 free checked bags up to 70 lbs.; bags can be checked no more than 4 hours before departure.
