I’m at MAT now flying up to Boston today… and it looks like I came on the last day! There’s a sign up that says all Boston flights are moving to B starting 7/9.
Security at the new B has been taking a lot longer than the old B (downside of centralized security checkpoints), so I’m going to miss the efficiency of the MAT. Today I went from the curb to the gate in less than 5 minutes.
