Firstly, I am not sure if this is the right place to post my questions, so i apologise in advance if it is not.
At the moment, i am planning to fly out from LHR back to MEL with SQ in late July 2018. (I have already redeemed a one way J ticket with SQ to LHR in June 2018.)
This is also my 1st time flying into LHR.
Some questions with regards to Heathrow T2 :
1) Does it take a long time to clear T2 passport control and security checks ? (I know SQ allows check in 4 hours prior to departure, so i guess that helps to lessen the stress)
2) Are the early morning departure flights busier than the late evening flights ? (I was planning to take the SQ305 flight which departs at 0925am)
3) Do SQ J and F class passengers have access to some kind of fast track immigration and security lanes for depature flights?
4) I am also considering flying out of AMS or ZRH with SQ. Do these airports offer a less stressful and more pleasant departure experience, compared to LHR T2 ?
Advance thanks to all replies.
