I'm a big boy (not fat, just big boned) and hate flying for the most part, because it's uncomfortable and being big and crammed into a small seat only exacerbates the claustrophobia. I can't afford business class and no telling if I can get exit row, and I definitely don't travel enough to use miles for any upgrades. What are the hopes for me on a flight to HKG from SFO, patience-wise? To be honest after about 2 hours on any domestic flight my back and legs start hurting pretty seriously and I get a little anxious. Just not sure how I can pull off the international 12 hour flight, but I'm still in my 20s so I think it's now or never, as the older I get the less patience I'll have for these types of flights. I'd like to go to Asia for my honeymoon next spring and getting a little tense about it already. Thanks for any input or suggestions.
