I've flown out of nearly 30 airports in nearly 60 years of flying and the
triple helix ramp design seems to be unique for T4, its not bad departing (downhill) but harder (as I get older) arriving (uphill).
Why would they design ramps like that?
Add in the "monster" size terminal, with moving "walkways" rarely 100% operational...make T4 a fun
terminal to use.
