Short, practical guides on booking, rules and what to expect at the airport.
Cheap flights checklist
The biggest airfare savings usually come from three things: moving your trip by a day or two, comparing nearby airports, and picking the fare type that matches the bags and flexibility you really need.
GuideBest time to book
For most domestic trips, booking roughly one to three months ahead gives a good balance of choice and price; for international and holiday travel, start earlier.
GuideBasic Economy vs Main Cabin
Basic Economy is the airline's cheapest fare.
GuideCanceled or delayed flight
If an airline cancels your flight or changes it significantly and you do not accept the alternative, U.S. rules generally entitle you to a refund to your original payment method.
Guide24-hour cancellation rule
U.S. rules require airlines selling tickets directly to let you cancel without penalty within 24 hours of booking, if you booked at least seven days before departure.
GuideInternational flight checklist
Before booking international flights, confirm your passport is valid for the destination's requirements, check visa and entry rules, and make sure your connection time suits the airports involved.
GuideREAL ID and passports
Since May 2025, travelers aged 18 and over need a REAL ID-compliant license or another TSA-accepted ID, such as a passport, to board domestic flights.
GuideBag basics
Baggage rules are set by each airline and depend on your fare, route and sometimes your status.
GuideHow early to arrive
A common rule of thumb is two hours before a domestic flight and three hours before an international flight, with extra time at busy airports and on holiday weekends.
GuideNearby airports
When a city has more than one airport, compare fares, ground transport time and schedule options, not just ticket price.
GuideLayover guide
For most domestic connections, 60 to 90 minutes is a realistic minimum, and 2 to 3 hours is more comfortable.
GuideName on ticket
The name on your ticket must match your government-issued ID or passport.
GuideFlying with kids
In the U.S., children under two can usually fly as lap infants on domestic flights, but everyone age two and older needs their own seat.
GuideTravel insurance explained
Travel insurance can reimburse non-refundable costs when you cancel for a covered reason and can cover medical emergencies abroad.
