What Are the 24-Hour Flight Change Rules for All Airlines?
By flightshelpcenter
Published on December 5, 2025
The 24-hour flight change rule is one of the most powerful tools available to travelers — allowing them to modify or cancel a booking for free within a specific timeframe. But even though the rule sounds simple, many travelers misunderstand how it applies to different airlines, ticket types, and booking methods. Some airlines follow the rule strictly, others offer variations of it, and some international carriers follow their own standards entirely.
This guide explains everything you need to know about the 24-hour rule, including how it works, which airlines follow it, which types of bookings qualify, and how to use the rule to avoid unnecessary fees. Whether you’re flying American, Delta, United, JetBlue, Alaska, Southwest, Air Canada, British Airways, Lufthansa, Emirates, Qatar Airways, or any other airline, this article breaks down the process clearly and thoroughly.
If you want someone to check your booking and confirm whether you qualify for free changes or cancellation, travelers can speak with a live specialist anytime at +1 (866) 558-3017.
Quick Overview: What Is the 24-Hour Flight Change Rule?
The 24-hour flight change rule allows travelers to cancel or change their flight for free within 24 hours of booking — as long as:
- The ticket was purchased directly from the airline
- The flight departs at least 7 days later
- The airline is based in or operates under U.S. Department of Transportation (DOT) regulations
This applies to every fare type, including:
- Basic Economy
- Non-refundable fares
- Discounted tickets
- International routes
Travelers unsure whether their fare qualifies can get fast confirmation at +1 (866) 558-3017.
How the 24-Hour Rule Works for U.S. Airlines
The DOT requires every U.S. airline to offer one of the following:
- 24-hour free cancellation, or
- 24-hour hold option before purchase
Most airlines choose free cancellation because it is simpler.
Airlines that MUST follow this rule:
- American Airlines
- Delta Air Lines
- United Airlines
- JetBlue
- Alaska Airlines
- Hawaiian Airlines
- Spirit Airlines
- Frontier Airlines
- Allegiant Air
- Avelo Airlines
- Breeze Airways
If you booked directly through any of these carriers, you automatically qualify — as long as your flight is more than 7 days away. To confirm your eligibility instantly, travelers can call +1 (866) 558-3017.
How International Airlines Handle the 24-Hour Rule
International airlines are not required to follow U.S. DOT rules unless:
- The booking was made in the United States
- The flight originates in the U.S.
- The airline voluntarily offers a similar policy
Many global airlines do offer a version of the rule, but the conditions vary.
Examples:
- Some allow 24-hour cancellation only for U.S.-origin tickets
- Some only allow same-day changes
- Some charge a small service fee
- Some exclude promotional fares
International travelers can confirm their airline’s version by calling +1 (866) 558-3017.
Step-by-Step: How to Use the 24-Hour Rule
Here is the expanded, detailed process for using the rule effectively.
Step 1: Verify Your Booking Timestamp
The 24-hour clock begins at the exact moment your booking is confirmed — down to the minute. If you booked at 2:43 PM, your window ends at 2:43 PM the next day. Many travelers mistakenly assume it resets at midnight, which is not always the case.
A specialist can check your remaining time if needed at +1 (866) 558-3017.
Step 2: Ensure Your Flight Departs 7+ Days From Purchase Date
The DOT requires the flight to be at least one week away. If your travel date is within 7 days, the airline is not legally obligated to honor a 24-hour refund — although some may still choose to.
Step 3: Confirm That You Booked Directly With the Airline
The rule applies to:
- Airline websites
- Airline mobile apps
- Airline reservation centers
It may NOT apply if your booking was through:
- Expedia
- Priceline
- Kayak
- Skyscanner
- MakeMyTrip
- CheapOAir
Third-party websites can choose to offer their own 24-hour policies, but it’s not legally required. If you’re not sure whether your booking qualifies as a direct purchase, call +1 (866) 558-3017.
Step 4: Decide Whether You Want a Change or Cancellation
Within the 24-hour window, you may:
- Correct spelling errors
- Change dates or times
- Rebook entirely different routes
- Cancel and receive a full refund
- Switch airlines after cancellation
The rule is especially helpful for fixing mistakes or taking advantage of price drops.
Step 5: Submit Your Request Before the Deadline
Acting quickly is essential. Some airline systems experience delays, and cancellation timestamps are based on the airline’s internal clock — not your phone or computer’s time.
If the airline website is down or not responding, call +1 (866) 558-3017 immediately so you do not miss your free-change window.
