Thanks for the info.
Say I have parents and extended family in Boston, but rent an apartment in Bangkok. Would that satisfy the 2nd city requirement?
As long as you present a lease, bills or any paperwork that proves you will be traveling there with some regularity they will accept it as a second destination for C class....
Now, the question is why would you do that? The months that you head down to BKK just bank the 2G's and use ZED tickets to get there, there are several flights a day and no jet lag issues to speak off, it's a roundabout 6 hour flight. Besides, most airlines that fly there make it with a configuration that is not lay flat so you won't be much more comfortable than in coach..., not $2,000 worth of comfort anyways
