Wed., May. 2 UA6 (NRT-IAH) - Canceled due to operational difficulties
Looks like the aircraft that was supposed to fly this route (N37018 - doing UA7 IAH-NRT) got diverted to SLC and SFO before getting sent back to IAH.
Friend was supposed to be on UA6 but got routed through SFO with the new Polaris seats, but no PJs because <10hrs.
