Pro Tips for Connecting at BOS
!BOS has a below-average on-time rate (77%). Add at least 30 minutes above the minimum connection time.
→JetBlue dominates Terminal C and is BOS's largest carrier. Most JetBlue connections stay within Terminal C.
→The connector between Terminals B and C lets you stay airside. All other terminal changes require the landside shuttle.
→Boston winters bring significant snow delays. Budget extra time for connections from November through March.
→Book both legs on the same ticket. If you miss your connection, the airline must rebook you at no charge. Separate tickets mean you're on your own.
→Choose morning flights for your first leg. Flights before 8 AM are delayed significantly less than afternoon flights.
→Avoid checking bags on tight connections. Carry-on only gives you maximum flexibility if you need to switch flights.
