and i would even take that further and say lie-flat business class or i don't cross an ocean.

when i was younger i flew long-haul Y all the time. then I was bitten with an upgrade to club world on BA YVR-LHR. that's a night flight and i simply can't sleep sitting up so jet lag would kill me. then after sleeping on a bed, 35,000 feet in the air, zooming around the planet with virtually no jet lag afterwards, i realized that i simply could not go back. i did have to once and it was such a miserable experience that basically i have adopted roberto99's philosophy, biz or bust.
