We booked a flight to Italy and a portion of our flight from London to Sicily has been canceled. We were suggested to purchase a second ticket as there was nothing else available with British Airways. So we did.
We now arrive in London at 10:15 am and need to go through baggage claim and customs and check in for a flight to Italy that leaves at 12:25 pm.
I am concerned about the time available to do all this. How long does it typically take and how long does it take to move from a terminal to another?
