you also should join the frequent flyer programe, its star alliance which gives you the choice of many airlines to get miles, and with Thai, if you get 50,000 in 1 yr ,they give you a gold card and a free upgrade voucher for any standard fare ticket you buy, i used my last one on a round the world ticket , which cost 1000 gbp (economy ) and flew business, which is pretty medioca in thai but much better than cattle and saved me 2k english, if i would have bought a business class ticket.
And your sure to be back in LOS to get those miles, so make em count buddy.
You can even get a silver card with Thai ( 20.000 )and when your in BKK you can get priority check in and an extra 10 kgs of baggage , comes in handy for taking all the cheap ciggies back
