We will arrive at London Heathrow at 7:05 am in Terminal 5 from Brussels. Our next flight will be at 8:30 am, also in Terminal 5. We have stopover of 1 hour 25 minutes, and we must be at our departure gate no later than 20 minutes before the departure time, giving use just about 1 hour to make the transfer time.
Is this enough time to make this connecting flight? What would happen if the first flight is delayed or it is busy going through Customs?
I've heard that it takes some time to go between Terminals 5a, 5b or 5c. How can I make this transfer as smooth as possible? Both flights are on British Airways and are booked as a single ticket.
