A quick follow up on my note from last night: Flying backwards really is not an issue (as several people pointed out), but there are 2 things to know about flying backwards in business class on the United 777-200:
1) Although flying backwards isn’t a big deal, TAKING OFF backwards means that you will face a barrage of crap flying by your head, including (but not limited to) a barf bag, an in-flight magazine (Hemispheres), a Skymall catalog, the dinner menu, napkins, your glass that the cabin staff forgot to pick up, your headphones, and the mint you left on the armrest.
2) Flying in a middle seat in business was not as big a deal as I thought, except that 3 times I woke up because I was touching (inadvertently) one of my seatmates. It was ever-so-slightly romantic and unspeakably horrible. Truly, truly horrible.
