What Information Do I Need to Book a Flight?

Quick answer

To book a flight you need each traveler's full name as it appears on government ID, date of birth, travel dates, origin and destination, and payment details. Preferences such as seating, baggage needs, and time-of-day flexibility help narrow the options faster.

The essential details

• Full legal name for every traveler, matching their ID
• Date of birth and, where required, gender as listed on the ID
• Origin and destination — city or airport codes both work
• Travel dates, or a flexibility range
• Payment method for the ticket

Helpful but optional

• Seat preferences (window, aisle, extra legroom)
• Baggage count, since allowances vary by airline and fare
• Frequent-flyer numbers for the airlines involved
• Special assistance or accessibility requests

A note on accuracy

Traveler names must match identification exactly. Corrections after ticketing can be limited or costly depending on the airline, so it is worth double-checking spelling before confirming any booking.
