Your flight time is listed on your booking confirmation and airline app, but "flight time" can mean different things depending on where you look
When you search for your flight, you will see a departure time and an arrival time. The departure time is when the aircraft pushes back from the gate — this is what airlines call "wheels up" or "off-block time". The arrival time is when the plane lands, not when you walk out of the airport. Between those two numbers sits the actual flight duration, which varies by route, wind, and weather.
Your confirmation email from the airline shows both times. Your airline's mobile app shows them too, usually with a countdown timer if your flight is within the next few days. If you booked through a travel site like Kayak or Expedia, log back in there and click on your booking — the times are stored in your account. You can also call the airline's customer service line and give them your confirmation number, and they will read the times to you.
Key Takeaways
- Departure time is when the plane leaves the gate; arrival time is when it lands — neither includes time to board, deplane, or collect luggage.
- Check your airline's app or your booking confirmation email first, because those are always current if the flight has been delayed or rescheduled.
- Airlines typically ask you to arrive at the airport two hours before domestic flights and three hours before international ones, so plan backwards from your departure time.
- If your flight time has changed since you booked, the airline will notify you by email or text, but checking the app yourself prevents missing a notification.
- Scheduled arrival time does not mean you can leave the airport when ready — add 30 to 45 minutes for deplaning and collecting checked bags.
Where to find your flight time if you booked online
Log into the website or app where you purchased your ticket. Most airlines — United, American, Delta, Southwest, Alaska, JetBlue — have a "Manage My Booking" or "My Trips" section. Enter your confirmation number and last name, and the system will show your departure time, gate number (once you check in), and current status.
If you booked through a third-party site like Kayak, Expedia, or Google Flights, go back to that site and find your booking in your account. The confirmation details will show the times. However, these sites do not always update in real time if there is a delay, so after you find your times there, also check directly with the airline's app to confirm nothing has changed.
How to find your flight time if you have only a confirmation number
Call the airline's main customer service number — you can find it on their website or on your booking confirmation. Have your confirmation number and last name ready. The agent will pull up your reservation and read you the departure time, arrival time, and any changes that have been made since you booked.
This method works even if you booked years ago and lost your email, or if you are traveling with someone else's ticket. It is also the fastest way if you need to know when ready and do not want to wait for a website to load.
What the times on your ticket actually mean
The departure time printed on your boarding pass is the time the airline expects the door to close and the plane to push back from the gate. You must be seated before this time. If you arrive at the gate after this time, you will not be allowed to board, even if the plane has not yet taken off.
The arrival time is when the wheels touch the runway at your destination airport. It does not account for taxiing to the gate, which can add 5 to 15 minutes depending on how busy the airport is. Once the plane reaches the gate, you still need time to deplane (usually 10 to 20 minutes for a full flight) and collect checked luggage (another 15 to 30 minutes depending on the airport).
Why your flight time might change after you book
Airlines adjust flight times for many reasons: weather, air traffic control delays, crew scheduling, or maintenance. When a change happens, the airline will send you an email or text notification if you provided contact information when you booked. However, not all notifications arrive when ready, and some people miss them.
The safest habit is to check your airline app or booking confirmation the night before your flight and again two hours before your scheduled departure time. This catches any changes the airline made and gives you time to adjust your airport arrival if needed.
How early you should arrive at the airport based on your flight time
Plan to arrive at the airport at least two hours before a domestic flight departure time and three hours before an international departure. This gives you time to check in, go through security, and reach your gate without rushing. If your flight departs very early in the morning (before 6 a.m.), arrive even earlier because security lines are often unpredictable.
If you are checking bags, add another 15 to 30 minutes to account for the check-in counter line. If you are flying from a very large or unfamiliar airport, add 15 minutes to account for walking distance to your gate.
What to do if you are unsure about your flight time
Do not guess. Call the airline directly using the number on your booking confirmation or their website. Have your confirmation number ready. The agent can tell you the exact departure time, whether it has changed, what gate you will use (though gates are usually assigned only a few hours before departure), and whether you are on the standby list if you booked a basic economy fare.
If you are traveling with a group or have a complex itinerary with connections, write down all your flight times and confirmation numbers before you leave home. Take a photo of your boarding pass once you check in at the airport, so you have proof of your flight details even if your phone dies.
Frequently Asked Questions
Can I change my flight time after I book?
Most airlines allow you to change your flight time for free if you booked a flexible or refundable fare. Basic economy fares usually charge a change fee plus any difference in ticket price. Log into your airline app, find your booking, and look for a "Change Flight" or "Modify Booking" button. If you do not see one, call the airline — some changes can only be made by phone.
What happens if I miss my flight departure time?
If you are not at the gate by the departure time, you will not be allowed to board, and your ticket will be forfeited. You will need to rebook on another flight, which usually costs a change fee plus the difference in fare. Some airlines will rebook you on the next available flight at no charge if the delay was the airline's fault, but if you missed your flight, it is your responsibility.
Does my flight time change if there is a delay?
No. The scheduled departure time stays the same on your ticket. The airline will announce the new expected departure time separately, and that is what you should use to plan when to arrive at the airport. Check your airline app for the most current estimated departure time, as it updates in real time.
How do I know if my flight time is in the morning or evening?
Airlines use 24-hour time on some tickets and 12-hour time (with AM or PM) on others. If your ticket shows "14:30", that is 2:30 p.m. If it shows "2:30 PM", that is the same time in 12-hour format. Your airline app will always show it clearly with AM or PM, so check there if you are unsure.
What if my flight time is very early and I cannot get to the airport in time?
Contact the airline as soon as possible. Some airlines offer standby lists for earlier flights on the same day, or they may rebook you on a later flight. You will likely pay a change fee, but it is better to arrange this in advance than to miss your flight entirely. Call the airline's customer service line, not the airport, because they handle rebooking.
