My two go to airlines out of BOS are Delta and JB BUT JB checked bag arrival in BOS is horrible. Usually around 30 minute wait but our last trip from SXM took 55 minutes .....after two gate changes and a two hour flight delay at JFK we finally took our 39 minute flight to BOS.
I emailed corporate at JB and recieved a call a few days later saying they were sorry for the baggage delay
Delta is usually the opposite...bags pretty quick.
