I've been to airports all over this world...and this is by far the worst thought out concept of one. Shuttles to opposite terminals are a bother but just be bold. The staff is pretty friendly.
If they take your handy suitcase on airplane door (no room inside) insist on "gate valet" so you'll get it back right when you of the flight rather than waiting on baggage claim
terminal 3 is relatively small...con: not a lot past security so if you're hungry get food before you head past security...pro: the line for security is never very long so you can usually breeze right
Big black guy just beat the shit out of his 3 year old daughter someone should beat the fuck out of him.. He is wearing a la dodger shirt and sitting at gate C11
