According to Boston.com, United Airlines plans to end flights from Manchester, NH to Chicago's O'hare National Airport.

So if you are someone who scheduled a flight from Manchester to Chicago after September 5th unfortunately, that will no longer be a thing.  However, you will be provided with alternate travel arrangements or a refund according to a statement made by United Airlines.

United will still be flying to Newark, New Jersey so connecting flights to Chicago can be made from there.

Have you ever flown from Manchester–Boston Regional? How does it compare to Logan Airport?
