I'm booking a ticket from JFK-BKK-JFK for this summer and have 50,000 miles that will be expired in June 2010. So, I am thinking about just buy K class ticket and request for an upgrade to Business class on the way back to Thailand.
Do you guys think that is possible to do so? or is there any suggestion for using this mile? I don't travel a lot (just home to college twice a year), so redeeming hotel voucher or something won't work, I guess.
Should I call or just upgrade through the website?
Thanks in advance
