If you can't find your flight confirmation email, the money has left your account and the one document proving the trip is nowhere you can see. Before you assume the booking failed, treat it as a filing problem: the email is a copy of your reservation, nothing more, and it is not the fastest way to get what you need.
Can't find your flight confirmation email? Start with three places
They are ordered so the quickest checks come first. Give each about a minute before moving on.
Search for the airline's name, not the word confirmation
The word you are probably typing may not appear in the subject line at all. Subject lines run to things like "your trip to Denver", "eTicket itinerary and receipt", or "you're all set", and a search for confirmation misses every one of them.
Search instead for what is certainly inside the message: the airline's name, the destination city, the three-letter airport code, the traveler's surname, or the exact dollar amount you paid. Searching by sender works too. Search behaves differently in every mail app, and filters narrow results in ways that are easy to miss, so if one query comes back empty, try a different shape of query before concluding the message was never sent.
Check spam, promotions, and any address you might have typed
Confirmations often travel through the same bulk sending systems as marketing mail, which is how one ends up under promotions, in a category tab, or in spam. Look in every folder your mail app has, archived and deleted items included.
Then consider another reason you may think the confirmation never arrived: you are searching the wrong mailbox. The address on the booking may be a work address, an old one, an alias your browser autofilled, a partner's, or one with a typo no search will surface. And if someone else made the booking — a colleague, a relative, a company travel desk — the confirmation went to them, and asking beats searching.
Look at the payment, not the mail
Open your banking app and find the charge. The merchant line names who actually sold you the ticket, which is the fork the rest of this article turns on: an airline name means you booked direct, anything else means you did not.
The charge also hands you two things worth writing down immediately, the exact amount paid and the date of purchase. Card descriptors sometimes carry a fragment of the ticket number as well. And if no charge appears at all, that matters too: a reservation that was never ticketed may not have produced the confirmation you are looking for, though some carriers do send a booking-received notice that is not the same document.
Find your trip without a confirmation number
Here is the step that tends to get buried. A lost flight confirmation is only a real problem if the email is the only copy of the trip, and it is not: the airline keeps its own record, and reaching that is usually quicker than another pass through your inbox.
Manage booking, with a surname and the card you paid with
Carriers generally publish some form of trip lookup, labeled something like "manage booking", "my trips", or "find your reservation". The standard way in is a confirmation code plus the traveler's surname, which is no help when the code was sitting in the email you cannot find.
So look for the alternative lookup underneath it. A second route in — by surname and travel dates, by the card used to pay, or by ticket number — is common enough to be worth hunting for, but which of those any given airline accepts varies and changes over time, so read your own carrier's page rather than expecting a particular option. If the lookup will not take what you have, that is the moment a phone call earns its place, rather than the last resort.
The airline app, if you were signed in when you booked
If you were logged into a frequent flyer account at checkout, the trip is generally attached to that account and shows up under trips in the app with no code required. It is often the fastest route in, and the one skipped by anyone still thinking in terms of email.
Booked as a guest? There is often a way to add a trip to an account afterwards, though it tends to want the confirmation code, which loops you back to the lookup above.
How to get an airline to resend your itinerary
Once the trip is on screen, a resend or "email itinerary" control is commonly somewhere on the trip page, and phone and chat agents can generally send a copy as well. It is a routine request and you do not need a reason for making it.
Two things to expect. Sending the copy to an address that is not already on the booking tends to be treated as a security matter rather than an administrative one, so be ready to verify who you are, and be ready to hear that the address on file has to be changed first. And ask specifically for the ticket receipt, not only the itinerary. The two are sometimes separate documents, and the receipt is the one that states what you paid and lists the ticket numbers. An itinerary on its own tells you when you fly, not what the ticket cost.
If you booked through an agency or a third-party site
When the statement named an agency, two separate documents may be in play: the agency's own booking confirmation and the airline's ticket record. Missing one does not mean the other does not exist.
The airline can often display the trip once the ticket has been issued, while the agency generally holds the booking, so a resend, a correction, or anything touching money tends to route back through them and on their terms. Check the agency's current terms rather than assuming they match the airline's, and see our piece on what changes when you book through an agency instead of the airline. A corporate travel tool behaves much the same way: the booking lives inside it, and a travel desk can usually reissue the paperwork for you.
What to do with it once you have it
Save the three identifiers
Copy these somewhere that is not your inbox, so the next search never has to happen: the record locator, the ticket number for each passenger, and the total paid with its currency and purchase date. While you are in there, note the fare brand printed beside each flight — reading the fare brand off your confirmation explains where it hides and why it matters more than the cabin name printed above it.
The one thing worth doing before you file it away
The price of the exact flight you booked does not stop moving once you have paid, and a drop is worth nothing to you unless somebody notices it before you fly. Doing that by hand means re-pricing your own itinerary on a schedule, which our guide to watching a fare after you have booked walks through honestly, including the part where the schedule quietly lapses.
If you would rather hand the message over and stop thinking about it, it is fair to want to know what is inside it first — we wrote up what a booking confirmation reveals and how to forward it safely.
You are holding it now, which is the hard part done. Adding the trip gives you an address to forward it to, and the fare gets watched until you fly — what happens after that is the short version.
Frequently asked questions
I didn't receive my booking confirmation email at all. Was the flight actually booked?
Check the card statement before you decide anything. A posted charge from an airline or a travel site tells you money moved, and it hands you the exact amount and the purchase date, which is what any lookup or phone agent will ask for. If no charge appears, a reservation may have been started and never ticketed, in which case there would be no confirmation to find. Either way your mailbox is the least reliable place to answer the question, because the address on the booking may not be the one you are searching.
How do I find my trip without a confirmation number?
Open the airline's trip lookup and read past the confirmation-code box. Carriers commonly offer a second way in, such as surname plus travel dates, the card used to pay, or the ticket number, though which options exist varies by airline and changes over time, so check your own carrier's page rather than assuming. If you were signed into a frequent flyer account when you booked, the trip is generally waiting in the app with no code needed. Failing both, a phone agent can usually locate a booking from your name, the route, and the payment details.
How do I get an airline to resend my itinerary?
Once the booking is open on screen, look for a resend or email-itinerary control on the trip page. Phone and chat agents can generally send a copy as well, and it is an ordinary request to make. Two things to plan for. Sending it to an address that is not already on the reservation tends to be treated as a verification matter rather than a clerical one. And the itinerary and the ticket receipt are sometimes separate documents, so ask for the receipt if you need the amount paid and the ticket numbers rather than just the flight times.
I lost my flight confirmation and I booked through a travel site. Who do I ask?
Start with whoever charged your card. When an agency or travel site is the merchant, the booking generally sits with them, so a resend or a correction usually routes through their support and on their terms; read their current terms rather than assuming they mirror the airline's. The airline can often still display the trip once the ticket has been issued, which is enough to confirm flights and times, but anything that changes the reservation typically goes back to the agency. A corporate travel tool or travel desk behaves much the same way.
