hi andypandy,
i am doing a similar travel from 2F to 2E soon. How long time did it take you finally? My connection time is 1 hr and 15 min. and i am afraid it is not enough given that I need to pass passport and security control at 11pm.

I do not know which gate in terminal E yet. But am I correct that E28-47 & E51-76 are reachable on foot?

Appreciate if you could tell me what is meant by land side and air side.
Thanks a lot!
