Pros: At least it was delayed so we could make it to SFO.

Cons: The American Airlines flight was delayed so the delayed flight from Honolulu could make it to Los Angeles and not subject AA to additional complaints. We arrived at close to midnight and worried about getting the car out of the parking lot without incurring additional charges of and additional day. The food was not great.
