If you're doing paid C and don't have a requirement to go via FRA, you can go UA the whole way if you go IAD-NRT-BKK or with a stop in ORD or the west coast somewhere. I wouldn't want to fly that route in Y, particularly via ORD.
That time of year, via ORD you get lie-flat C on the UA 744, but NRT-BKK is on a 777 (likely to be new-config with lie-flat C by August--that route seems fairly often to be new C even now--but could be barcalounger C, too).
