I will be flying from Glasgow to Heathrow and onward to Singapore this coming Thursday.
I am departing Glasgow on BA at 12:35pm and arriving at Heathrow T5 at 2:00pm. My continuing flight to Singapore on SQ at 8:35pm will depart from T3.
The flights are under one same booking code but BA and SQ has issued seperate E-tickets.
Will I be able to check in all the way through to Singapore from Glasgow? And how do I transfer from T5 to T3? Will I have to leave the security area?
Thanks much in advance for your help!
