I don't appear to be able to browse much more at this time. Try again later, please. However, I can disclose that Boston Logan International Airport's Terminal B is normally where Sun Country BOS Terminal operates (BOS). Sun Country passengers can use this terminal to check in, drop off their bags, and board their flights. Make sure you verify the gate you are in and keep an eye on the airport screens for any flight-related changes. Please let me know if you require any further details!
