I am flying from Maui to London and have a layover at Seattle for nearly 13hours. The flight will all be booked on the same ticket (Virgin or Delta). I believe the bags will be checked straight through from Hawaii to London and will not need to be collected at Seattle. Presumably as Maui - Seattle is a domestic flight I will not need to go through customs? Could someone please confirm whether I am able to leave the airport and take in a few sights rather than hanging around at the airport? Also, is it realistically worth doing that with the amount of time I would have? (I realise this will involve going through security again for the SEA-LON flight).Thanks in advance!
