Houston · airports: IAH, HOU
Compare both airports when you look at fares, and keep weather in mind if you travel in late summer.
New York · airports: JFK, LGA, EWR
Winter storms and summer thunderstorms are the usual causes of delays, so leave extra connection time in those seasons.
San Francisco · airports: SFO, OAK, SJC
Fog can cause delays at SFO, particularly in the morning. Check all three airports when you compare fares.
Los Angeles · airports: LAX, BUR, SNA, LGB, ONT
If you are flexible about airports, ask for prices into more than one of them. Fares and schedules can differ noticeably.
