How do I book a domestic flight?
How domestic flight booking works step by step — and where a phone agent fits in.
Quick answer
Booking a domestic flight comes down to five steps: pick your airports (including nearby alternates), settle dates or a flexibility window, compare available fares and their rules, enter traveler names exactly as on ID, and pay. You can do this on any airline site — or share the details with an agent and have the comparison done for you.
Worth knowing before you book
- The cheapest fare tier often has the strictest change and cancellation rules
- Nearby airports can price very differently on the same dates
- Baggage, seat selection, and same-day changes are priced separately on most fares
