I have a short connection at LHR in route to Glasgow. I arrive on American Airlines at Terminal 3 but depart for Glasgow from terminal 5. I understood from reading other forum comments that I need to go through immigrations at Terminal 3 before going to Terminal 5. Everyone has suggested using the e-gate to speed up the process.
Where are the e-Gates located in terminal 3?
After completing the e-gate process, is taking the Heathrow Express to Terminal 5 the quickest option?
Thanks.
