I have a flight from Zürich to Heathrow scheduled to land in Terminal 2 at 17:55, transferring to a flight to Ireland also out of Terminal 2, scheduled to depart at 21:10.
I will not have any checked bags - should I be able to make this connection in time, and will I have to leave the secure area as a normal arrival, or can I take the connections line, assuming that I have my boarding pass printed?
