英國轉機去日內瓦

For BA flight from Hong Kong, you will arrive at Heathrow Terminal 1.

Then for flight to Geneva, you will depart from Heathrow Terminal 4.

Heathrow Terminal 1 and 4 are two different building, 15 minutes apart. So as soon as you leave the flight, you will need to contact the ground staff (waiting at the gate), then follow the transit sign and catch the connection coach (free of charge). You should not need to collect your luggages unless otherwise been told.

There is also heathrow express connecting terminate 1 and 4. Also free of charge.
