While accurate, I think at this stage that is now a technicality and will largely be lost on the millions of people who have seen that video.
It's going to cost United a fortune. Mind you, given my experience of flying United from the states (no seat-back entertainment - just TVs on the ceiling showing 'My Big Fat Greek Wedding' on a constant loop - this was in 2012 - and they lost my bag), I would be happy to be given a grand and fly with someone else.
I used to regularly take a Pan Am flight from Heathrow to Frankfurt, which originated in New York and stopped at Heathrow for fuel. The reason it couldn't get all the way to Frankfurt in one hit was that it was the world's oldest 727, rattling its way across the pond years after it should have been relegated to flying contraband in West Africa.
