I need to go to Asia for business. I can leave from almost any airport in the US (I live in Ohio but the office is in Oregon). I think my plan is to go into either HAN or BKK and out of the other. I would prefer AA or One World as I have AA miles I can use to upgrade but I am open to other airlines/aliances. Since this will be a long flight no matter what route I take I am looking for recommendations for the best airlines, equipment, seats, food, etc. I can download entertainment so IFE is not my biggest concern. Thanks
