I'm flying from Pakistan to Canada, I do have a stopover in UK of 4 hours. My flights lands on terminal 3 and my next flight is from terminal 2. I have booked directly with Air Canada and flight has been codeshared with Etihad Airways until arrival at London Heathrow. From London Heathrow, it is with Air Canada.
I want to know, in my situation do I need a transit visa to move from terminal 3 to 2, or just for any other case, in my situation do I still need it?
Looking forward to early responses.
