How should I book a United Airlines flight?
United booking choices center on cash fare type (Basic Economy vs Economy/Economy Plus), MileagePlus Award Travel, and Money + Miles hybrid payment. Basic Economy is the restricted saver fare—usually no free carry-on, assigned seats, changes only by cancel-and-rebook. Money + Miles lets any member with miles chip in miles at checkout on United, United Express, and select partners (including Basic Economy on select flights). Eligible United co-brand cardmembers can also cut award prices (10%+, 15% for Premier) when booking with miles.

- Live prices and award availability come from the airline site at booking time
Important unknowns
- Detailed award chart / dynamic pricing rules.
