Jennifer Jones, 69, is on a layover at Heathrow from Phoenix, Arizona, and said: “(We) had to wait on the plane for the bus to come get us because everybody was trying to get on the buses, so we finally got on the bus and got inside, and it was chaos because everybody’s flights were cancelled, and by the time we figured out ‘well, I’m going to have to stay the night’, the hotels were all booked.”
