The difference between Bangkok and NYC:
Trains are newer in BKK
Roads and Traffic are better in NYC
Everything is cheaper in BKK
I have been forced by various factors to fly in an out of NYC recently and JFK is horrendous although transport in and out of the airport is easy, and expensive.
Here is my airport list for international travel over the past three years.
Frankfurt: dingy, under construction, long walks, rude staff, depressing with all the Hijabs and machine gun toting Cops, including a blonde one that was so hot I started staring, and when she asked me in English if she could help me (yeah baby, rip off my clothes and take my virginity) I had to beg off and tell her I was looking at her MP5.
JFK: Huge and getting huger, good transport within airport to cut down walks, but its old and dingy and under construction.
Swampy: Nice and clean, well organized long walks between gates though
DMK: It works. Easy to get around, great transport to Downtown
Istanbul: Inflation, long walks, rude staff. Food is good till you get the bill.
Seoul: Heaven on Earth
Singapore: I've only walked from one Gate to another. I like their security setup (at Gates).
Dubai: OK, Ive only walked from gate to gate. I avoid Arab countries if I can, tough to keep my buzz going on the long trip.
Shanghai Pudong: Just freaking huge. Dont expect a fast transfer.
Paris: Its got French people.
Taipei: Horrible food.
Siem Reap: Huge Chinese boondoggle in the middle of rice fields, why in an empty airport do I have to walk past 17 empty gates? $80 DMK-SAI, then $25 into town. Yeah, thats the way
