I just remembered some comments the captain on our flight from LA to Chicago made about our delayed departure and change of planes.
He explained that there was a technical problem with the plane we were scheduled to use, as it had been having problems with cabin pressurisation. He thought we might all have trouble holding our breath for 4 hours on the flight to Chicago, so got us another plane to fly on. Nice of him.
