I've flown TG MD-11's in 1st twice: BKK-LAX in the mid-90's, and BKK-AMS in '98. The 1st class seats are among the most uncomfortable I've ever encountered; the biz. seats are the old ones, and they've not upgraded the cabins. Service is always good, but they really need to get rid of the MD-11's if comfort is any criteria.
