It's a good idea to confirm flights up to a week in advance, and acceptable even to check a second time up to 24 hours before flying. Doing so enables you to double-check flight information, request special meals, book a particular seat and alert the airline of any special needs or medical conditions. You can call the airline, use the airline's website or visit the airport in person to confirm flights. Many airlines provide flight updates by text for smartphone users.
Gather flight information. This includes your airline, flight number, destination and time of departure.
Call the airline. A toll-free call to customer service is the most common way to confirm a flight. This number is usually listed on an airline's website or ticket booklet.
Visit the airline’s website and follow the links for flight confirmation. Large carriers often have electronic options for confirming flights.
Visit the airport. If you prefer talking to a person face-to-face, visit your airline’s ticket counter at the airport of your departure. Bring a photo ID and all necessary documents with you.
