Airline and third-party ticket vendor sites, such as Expedia, allow users to verify reservations by entering the confirmation code and last name. Another option is to call the airline's customer service number to get confirmation.
Travelers often have the option of creating accounts on airline websites. Upon logging into the account, the user sees a list of upcoming trips purchased with the airline. This list allows the user to check itineraries and verify reservations. Discount travel vendors have similar options.
Clicking on a reservation listed on the website pulls up the specifics of the trip. Travelers use this information to verify the date, time and gates for the reservation.
