Tonight my wife was flying Dayton – Dulles – LaGuardia on United metal. Her flight into Dulles was a few minutes late, and when she arrived at the gate for the flight to LaGuardia, they told her they just shut the doors (10 minutes before departure) and she could not get on. This was the last flight of the night out, and the plane was spending the night at LaGuardia.
My question: is this normal procedure? I’ve never misconnected on the last flight of the night, so I wasn’t sure.
