How much does it cost to change a United Airlines flight?

Changing a flight is something most travelers deal with at some point—unexpected plans, emergencies, cheaper deals, or simply wanting a different schedule. If you’re flying United Airlines, the good news is that the airline offers flexible change policies on most fares. However, the total cost to change a United flight depends on several factors, including the type of ticket you purchased, your destination, time of change, and fare differences at the time of rebooking.

Understanding United Airlines’ Flight Change Policy

For several years now, United has eliminated many traditional change fees, giving passengers more flexibility. However, this does not mean every ticket can be changed for free, nor does it guarantee that you won’t pay anything for switching your plans.

Here’s a quick overview:

Most standard tickets have $0 United change fees
Basic Economy tickets generally cannot be changed, except under special circumstances
Fare differences still apply — even if the change fee is $0
Same-day flight changes may have a reduced or waived fee depending on status
International and partner-operated flights have different rules
Award tickets (MileagePlus) have flexible, free changes
Weather, illness, or schedule disruption waivers may remove fees entirely

Now, let’s explore these in detail.

1. Change Fees for Different Types of United Airlines Tickets

Basic Economy Tickets

Basic Economy is the least flexible fare on United Airlines.

Standard rule:
Not changeable
Not refundable

However, there are exceptions:

When can you change a Basic Economy ticket?

If you purchased Flexible Booking as an add-on (available in some markets)
If United issues a schedule change or flight cancellation
If you purchased the ticket with travel waiver provisions under special events
If traveling on select international Basic Economy routes that allow paid changes

Cost to change a Basic Economy ticket:

If allowed, expect to pay approximately $99–$199 plus any fare difference
Some international routes may charge up to $250

Basic Economy has the highest restrictions, so flexibility is limited.

2 Standard Economy Tickets (Economy, Economy Standard, Economy Fully Flexible)

Great news — United has permanently removed change fees for most domestic and short-haul tickets.

Change fee:
$0 for all domestic flights
$0 for flights to Mexico, Canada, and the Caribbean
$0 for flights originating in the U.S.

Only the fare difference applies.

For example:

Original ticket: $280
New ticket price: $350
You pay: $70 fare difference

If the new flight is cheaper:

You may receive a travel credit (ETC).

3 Premium Cabin Tickets (Premium Economy, Business Class, Polaris)

All premium fares on United are extremely flexible.

No change fees
Only fare difference may apply
More same-day options

Premium fares often have lower fare differences because the class availability is broader.

4 International Tickets

For transatlantic, transpacific, and long-haul flights:

Most standard international fares have no change fees
Some discounted international economy fares may still have change restrictions
Premium international fares usually offer free changes

Typical cost:

$0 change fee
Fare differences vary widely ($50–$900+)

5 Award Tickets (MileagePlus)

United has one of the most flexible policies for award tickets.

No change fees on award tickets
Redeposit fees removed
Fare difference = miles difference only

Example:

Original flight: 10,000 miles
New flight: 15,000 miles
You pay: 5,000-mile difference

If the new flight costs fewer miles, you get some miles refunded.

Same-Day Flight Change Fees (United Same-Day Change)

Same-day flight changes allow you to switch to another flight on the same calendar day.

Even though United has eliminated many change fees, fare differences remain the main cost for most passengers.

What is a fare difference?
