LAX is the worst choice you could make for your vacation. It is dirty, decaying, crowded, rude, badly maintained, dingy, depressing and disgusting. Calcutta in the monsoon season is nicer than LAX on a good day. Save your vacation, and avoid LAX.
John Wayne (SNA) is the anti-LAX. Clean, new, modern, spacious yet compact, friendly, stylish, easy and accommodating. You pay a bit more for most flights into John Wayne, because it's so fresh and fun and nice. But it's worth it. And if you've found a good fare using John Wayne, grab it and don't look back. It's also about a 20 minute drive to Disneyland from John Wayne baggage claim. Super easy, super fast. Orange County simply trumps Los Angeles County, and their airports prove it.
And for gosh sakes, the airport is named after...
John Wayne! With a giant bronze statue of the Duke right near the Hertz counter. How can you not love that?!?
Long Beach Airport is a close second, with a ultra-hip new terminal and very convenient layout. It's about 25 minutes from the Disneyland Hotel door to door. But Long Beach is primarily used as JetBlue's major West Coast hub, with a few Alaska, American or United flights thrown in. If JetBlue doesn't fly out of your city, it's probably not worth it to use Long Beach.
Burbank Bob Hope or Ontario airports are decent backup choices.
FUN FACT: About five years ago the Ontario city council considered renaming their Inland Empire airport
"Walt Disney International" in an attempt to steal some of the Disneyland tourist traffic from LAX and John Wayne. The locals protested as there was no evidence that Walt had ever visited Ontario, and the Orange County airport authority also lodged a complaint, and the idea was quietly shelved.
But whatever you do, if you value your sanity and your health and your vacation time, do
NOT book a flight into or out of LAX. It's the worst airport in America, if not the entire Free World. LAX is probably a tad nicer than the airport in Pyongyang, North Korea if only because the passport control officers are slightly more humane at LAX and the duty free shops at LAX carry Jack Daniels, but that's about all it has going for it over Pyongyang. And I'm only slightly exaggerating.
