It was 10 hours. Sometimes it can be more; it just depends on how the weather is. Back is overnight and it was about 9 hours. It wasn't too bad. United does a direct flight from Dulles to Honolulu, and for some reason, it was cheaper than stopping.
So we made the trip from Baltimore down to Dulles.
If you ever get out there, make sure you pack allergy meds and up your allergy medicine a week beforehand. They have some different plants that can aggravate those of us who aren't used to them on the East coast. This was my allergist's advice to me since I'm going back in June
(I know, we just went, but I wanted to go to Disneyland, and then somehow we had points we had to use or lose, so my dad said, "You wanna go to Aulani?" and who am I to say no?
