I just booked my first flight heading out of the country (going solo), and I have a couple questions about the steps I need to take to calm my nerves. I’ve flown two previous times, and I have no issues or fears with flying itself. It’s just that build up to it. I’m just at a complete loss for how things work when going out of the country.
I'll number my questions so it's easier to answer.
At what point to I go through customs/show my passport? My flight is PIT (Pittsburgh) to IAD (Washington, DC - Dulles International). Then I change planes, and continue from IAD to LHR.
Do I have to pick up my bags when I change planes (it’s United Airlines the whole time) and go through the process again?
After arriving at LHR I'll be catching a bus that departs from the Central Bus Station at 11:10am. My flight is scheduled to arrive at 10:20am. Did I leave myself enough time?
