We first learned from passengers what happened on board the United flight where a passenger was dragged off by Chicago Aviation Police and bloodied in the process.
This week, through released documents, we learned the Police version of events.
United has provided its detailed play by play in a letter to members of the Senate Commerce Committee (.pdf)
United CEO Oscar Munoz opens by defenestrating himself before the Senators (“I understand the Committee’s strong interest in this incident and appreciate your important oversight role”).
Then they offer substantial detail. They offered up to $1000 in travel credits to passengers willing to get off the flight voluntarily. The crew members flying to Louisville had been booked on a different, delayed flight which they weren’t sure was going to fly but that ultimately did close to midnight. (Had they taken this flight it would have meant delaying the morning flight back due to FAA required rest.)
