Hi we are planning a trip to Cuba. We arrive Lax at 6:30am on qantas from Sydney. We are looking at a flight by Alaskan airways that leaves at 8:50am to Havana .I think this is from terminal 6. Because this flight to Cuba when does the checkin close due to travel restrictions on Cuba flights. We have hand luggage only and plan on using the kiosks at tom Bradley to clear customs. Will we have enough time? Do we need to go outside tom Bradley and clear security again or is there away to get to terminal 6 remaining airside.
