LAX is consistently rated as the worst airport in the USA. Sometimes it's only rated second worst. It's decrepit, confusing, dirty, overcrowded, and at Midnight with no traffic it's 45 minutes from the Disneyland Hotel. Anytime between 7AM and 8PM with traffic, it can take well over an hour. Sometimes two. And they closed the Imagineering-designed restaurant in the fabulous Theme Building, LAX's sole redeeming quality. (Seriously, Walt Disney Imagineering designed and built a wild Jetsons restaurant in the LAX Theme Building back in the 1990's, but the Los Angeles Airport Authority closed it last year. Idiots.)
John Wayne Airport (airport code
SNA) is the "local" airport for the 3.5 Million people that wisely live in Orange County instead of Los Angeles County. John Wayne is 15 minutes from Disneyland without traffic, 30 minutes with traffic. It's brand new, clean and safe, attractive, compact but served by all major airlines, and located literally at the end of the the freeway offramp off the San Diego Freeway.
LAX is WalMart on a bad day. John Wayne Airport is Nordstrom. Remember that.
A good second choice if you live in a JetBlue city is Long Beach Airport (airport code
LGB). Only slightly further from Disneyland than John Wayne, it's also a brand new terminal with very easy freeway access and vastly easier and cleaner and calmer than LAX. Delta/American/United/Alaska also fly to LGB, but it's JetBlue's West Coast hub with JetBlue non-stops to the East Coast.
LAX was last a relevant, modern airport sometime around 1974. Avoid LAX like the plague, and your SoCal vacation will be that much better.
