British Airways planes are parked at Heathrow Airport during a 48hr cabin crew strike in London, Tuesday, Jan. 10, 2017. British Airways cabin crew members and Southern Railways train drivers walked off the job, touching off fresh disruption for travelers in Britain. The strike came a day after a subway strike snarled transport across London as unions increasingly show a willingness to walk off the job in disputes. (AP Photo/Frank Augstein)
Flights are delayed for all kinds of reasons: but a mouse on board isn’t usually one of them: Someone saw a mouse, and airline rules say you can’t fly with a mouse on board….they could gnaw thru wiring…so passengers were delayed for four hours while British Airways found another plane.
