HKG-SIN continuing to struggle this week after earlier cancellation on Monday.
Wednesday left 30 min late, sat on taxiway for a while, captain announced return to gate due to maintenance, then the problem cleared up on taxi back to gate so we looped around and took off. I guess "only" an hour late isn't bad. But flight was packed--saw at least 20 new BPs at gate stand, op-ups galore I'd guess.
