I am looking to fly JetBlue out of Newark or JFK but what California Airport is the closest to Disneyland to fly into. Also I could avoid LAX very easily if possible!
Long Beach Airport is the closest airport to Disneyland that Jetblue flys into. The website for the LGB airport is http://www.longbeach.gov/airport/ where you'll be about 15-20 miles from Disneyland, depending on which route you take to get to the Magic Kingdom. The airport is basically between Disneyland and LAX, and it is definitely less crowded than LAX.
I'm flying from JFK to Jet Blue this Saturday. They had the best rates and even though JB flies into other airports out there, LB had a better selection of times.
