I have a flight booked with UA from Dulles arriving LHR 06:20 on a July Sunday morning to terminal 2. I then have an onward flight with BA from Terminal 5 to Bergen. I will be travelling with bags. The flights are two seperate tickets- no code sharing. I assume that I will have to go through passport control, collect my bags, go through customs, transfer, check in, go through security and get to the gate. (or am I mistaken). Is there any posibilty that this would work or is it a no hoper.
