Try "Cincinnati" to Frankfurt, Germany with a constant plume of smoke. Or Brussels, Belgium. Gag. Add the BO from the "bath a month" club and you have a very malodorous transit. I only tolerated it because it was a business trip on the company nickel. There's no way I would pay out of my own pocket for that experience.

EWR to Tokyo was awful...14 hours! The Asians were the worst!
