EWR-BKK would be a great addition. As someone mentioned earlier, it would rival the EWR-SIN on Singapore Air as one of the longest flights ever. I never got to take advantage when Thai Air had their JFK-BKK route. They had to remove seats like Singapore Air did in order to lighten the load factor so the plane could fly that far. Too bad Thai Air killed that route. Probably in part their fault for refusing to market, codeshare or grant points with UA.
I also noted like others that the merger site is missing BKK, SIN, TPE, SGN, etc. Quite obviously the webbies used a quick & dirty CO interactive route map and forgot about UA's Asian direct & connecting flights from its NRT hub. The merger pdf has them all.
