Didn't nonrev out of BKK so not sure what the procedure is. Had some leftover UA/CO miles and was able to redeem miles for a o/w first class ticket on TG to NRT then non-revved in First on AA back to the US. It was quite an unforgettable experience. One final Thai massage in the TG FC lounge anyone? Decided to spend 2 nights in NRT at the last minute as it was cherry blossom season. If you've never been to Tokyo, you should spend at least a night or two to check it out. This was our second trip to NRT so we stayed at one of the NRT hotels. The AA hotel didn't have any rooms available so we stayed at the Crowne Plaza. They offered a reasonable airline discount. The train from NRT to Tokyo took about an hour.
