Yes, you can change your Alaska Airlines flight, but the cost and process depend on your ticket type and how far in advance you make the change

Alaska Airlines allows you to change your flight through their website, mobile app, or by calling their reservations team at 1-800-252-7522. The airline does not charge a change fee, but you may owe the difference in fare if your new flight costs more. If your new flight is cheaper, Alaska does not refund the difference — it stays as a credit in your account.

The ease of changing your flight depends on whether you booked a Basic Economy ticket or a higher fare class. Basic Economy tickets have the most restrictions: you can change them, but only to a flight on the same day or within 24 hours of your original departure time. Standard and premium tickets give you more flexibility to pick any available flight on any date.

How to change your flight online or through the app

Log into your Alaska Airlines account on their website or open the mobile app. Select "Manage My Booking" and enter your confirmation number and last name. Once your reservation appears, click the flight you want to change and select "Change Flight."

The system will show you available flights on the same route. If you are changing a Basic Economy ticket, only flights within 24 hours of your original departure will appear. For Standard or premium tickets, you can see all available flights. Select your new flight, review the fare difference, and confirm the change. Your new itinerary and boarding pass will appear when ready in your account.

If you cannot find your preferred flight in the search results, it may be fully booked or not available on that date. In that case, you will need to call reservations to explore other options or waitlist for a sold-out flight.

Changing your flight by phone

Call Alaska Airlines reservations at 1-800-252-7522. Have your confirmation number and last name ready. A representative will pull up your reservation and show you available flights that match your ticket type restrictions.

The representative will tell you the new fare before you confirm the change. If you owe money, you can pay by credit card over the phone. If your new flight is cheaper, the credit stays in your Alaska Airlines account and does not go back to your original payment method. Phone changes take a few minutes, and you will receive a new confirmation number and updated itinerary by email.

What happens if your new flight costs more

When you change to a flight with a higher fare, you pay the difference. For example, if your original ticket cost $150 and your new flight costs $200, you owe $50. You can pay this difference when ready online or over the phone when you make the change.

If you change your flight more than 24 hours before departure, you will see the exact fare difference before you confirm. This gives you a chance to decide whether to proceed or pick a different flight. If you change within 24 hours of departure, the fare difference calculation works the same way, but your options are limited by Basic Economy rules.

Understanding Basic Economy restrictions

Basic Economy is Alaska Airlines' lowest fare class. These tickets come with stricter change rules than Standard or premium fares. You can change a Basic Economy ticket, but only to another flight on the same day or within 24 hours before your original departure time.

This means if your flight departs at 2 p.m., you can change to any Alaska flight departing between 2 p.m. the previous day and 2 p.m. on your original date. You cannot change to a flight the next day or later. If you need to change to a different date, you would need to purchase a new ticket rather than modify your existing one.

Basic Economy tickets also do not include a carry-on bag or seat selection, though these restrictions are separate from change rules. The change window is the main limitation you will encounter.

Standard and premium ticket changes

Standard and premium tickets (including First Class) have no time window restrictions. You can change your flight to any available flight on any date in the future, as long as seats are open on your chosen route.

These higher fare classes also include other benefits like free seat selection, priority boarding, and checked bags, which carry over to your new flight. If you change to a flight that departs sooner, you keep all the same benefits on the earlier flight.

What to do if your preferred flight is full

If the flight you want to change to is fully booked, you have two options. You can select a different available flight, or you can ask to be placed on a waitlist for your preferred flight.

Waitlists are free and automatic — you do not need to call or do anything after requesting one. If a seat opens up due to a cancellation or no-show, Alaska will move you to that flight and send you a confirmation email. Waitlists can take hours or days to clear, so book a backup flight if you need to travel on a specific date. If a seat opens on your waitlisted flight before your backup flight departs, you can switch to it at no extra cost.

Frequently Asked Questions

Can I change my flight the day before or day of departure?

Yes, but it depends on your ticket type. Basic Economy tickets can only change within 24 hours of the original departure time. Standard and premium tickets can change to any available flight on any date, including the same day. Call 1-800-252-7522 if you need to change within a few hours of departure, as phone agents can process changes faster than the website.

What if I want to change to a completely different route, not just a different time?

You can change to a different route if your ticket type allows it and seats are available. Standard and premium tickets can change to any Alaska Airlines flight. Basic Economy can only change within the 24-hour window, but the new flight must be on the same route. If you need a different route on a Basic Economy ticket, you would need to purchase a new ticket.

Do I lose my money if I change my flight?

No. If your new flight costs less, the difference becomes a credit in your Alaska Airlines account that you can use for future bookings. If your new flight costs more, you pay the difference. You cannot get a refund to your original payment method, but the credit never expires as long as your account remains active.

Can I change a flight I booked through a travel website or airline ticket counter?

Yes. Flights booked through third-party travel websites or at an Alaska Airlines ticket counter can still be changed through the Alaska website, app, or by phone. You will need your confirmation number, which should have been sent to your email when you booked. If you cannot find it, call 1-800-252-7522 and provide your name and flight details.

What if Alaska cancels my flight — do I have to pay to change?

No. If Alaska cancels your flight, you can change to any available flight at no charge, regardless of fare difference. Alaska will also rebook you automatically on the next available flight to your destination if you do not make a change yourself. You can still choose a different flight if the automatic rebooking does not work for you.
