JetBlue at BOS: check-in and bags 45 minutes before domestic departures and 60 minutes before international.

BOS tips first-timers miss

  • Terminal A is not connected to the other terminals after security. If you are in the wrong terminal, you will have to clear security again.
  • Uber and Lyft drop you at the Central Parking Garage for Terminals A, C and E, not at the curb. Allow a few extra minutes to walk in.
  • The Silver Line SL1 runs directly to every terminal from South Station. Massport says it is free from the airport to downtown.
  • Runway 9-27 work through November can cause afternoon and evening delays. Check your flight status before you leave.
  • Logan garages fill earliest on Tuesday and Wednesday mornings, so pre-book parking if you are driving
