Hi all,

I'll be travelling from ARN-LHR (SAS) and LHR-YUL (AC) on 2 different tickets on the same day. They'll both be using Terminal 3 at LHR. If I don't have checked luggage, can I stay inside security and check-in for my LHR-YUL flight at the gate? Or must I go outside, check in, and come back?

I'm deciding between 2 ARN-LHR flights that will either result in a 4hr or 1 hr layover. Will 1 hr be enough?

Thanks for your input.
