Looks like UA goofed up this past weekend as the reservations system allowed pax. to redeem miles for a trip to HKG for as little as "4 miles"!!! Department of Transportation is telling UA tough luck because you have to honor every seat that was awarded.
"A new government rule bans price increases on tickets after they're bought unless government-imposed taxes go up."
Gosh, I wish I was trolling the UA Mileage Plus site this past weekend.
