I'll throw in my vote for O'Hare but from my experience, most US airports aren't great.
Often see Asians getting schtick from mostly black airport staff, who obviously detest their jobs and enjoy derisive mouthing off.
Once saw a 30something year old Japanese man with his 5yr old and 60s mother, being pushed around possibly because he couldn't comprehend them speaking English so fast. Literally tore the jacket off him, all while spewing acid sarcasm, then laughing it up amongst each other knowing full well he won't understand a word. Utterly disgusting behaviour.
I myself regularly get the whole works, the stand-aside and wand treatment. Used to it already
After the long ride, I always shake my head and shudder; I really don't need this right now.
Thank goodness I'm pretty tolerant, chanting to myself don't give lip, they gotta let me through sooner or later.
Agree with poster up above, be thankful for that Sg passport.
I hold a Msian one, and that's a real chore in the US.
As for my O'Hare story: they detained me for 1 hour, in 3 separate areas, with 3 different officers asking me the exact same questions I answered when I processed my visa! Thumbprint, photo, and a game of 20 questions.
Agonisingly, I watched my bag make its meandering laps on the carousel.
After the next enclosed room, poof, missing luggage
Barely made it to my connecting; at least still had my wits to tell the international side to ring up their domestic and tell them I was rushing over.
The flight attendant was holding on to the door, and slammed it shut right behind me as I rushed/ran/sprinted through the aisles and then the flight tunnel.
Worst hour of my life, on a plane, wondering where my luggage would be (my dressy clothes for conference were in the bag), adrenaline pumping, couldn't sleep eyes wide open.
Silver lining: at least I had my DSLR with me. Also found out that no matter how heavy I always complain my camera bag is, it was practically weightless when I was running from terminal to terminal
Filled in a report, and got an apologetic bag of toiletries to last through the night, bleah.
There's a happy ending though, they located it in Chicago and shipped it back to me the next day. All intact, phew. The return flight and the others on the other hand, well that's another story...
*My friend tells me TSA recently had a lightbulb flick on, kindness campaign and all, now they're sugar and spice. Won't hold my breath for that next trip... hope the Grand Tetons next year are worth braving all this again
