The rest of the passengers deplaned and were bused to the terminal. They were put on a flight to Boston, which landed at Logan Airport around 4:30 a.m. Wednesday.

“United flight 1888 traveling from Houston to Boston was diverted to Washington Dulles in response to a medical emergency on board. Medical personnel met the aircraft at the gate. We are saddened to learn that our customer passed away and we extend our sincerest condolences to the family.”
