Flying from Boston: what you need to know
Logan Airport has a geographic advantage that most people overlook: it's the closest major U.S. airport to Europe. That means shorter flights, less fuel, and sometimes lower fares. Boston to Dublin is under 6 hours, and Boston to London is barely over 6.
JetBlue is the hometown carrier — its Mint business class product launched here, and the airline competes aggressively on both domestic and transatlantic routes. Delta and United also have significant operations. On the budget side, PLAY (via Reykjavik) and Icelandair offer connecting service to Europe starting around $300 roundtrip.
The Irish routes are Boston's crown jewel. Aer Lingus runs multiple daily nonstops to Dublin and Shannon, and the Boston-Dublin fare war is legendary — sub-$350 roundtrips appear regularly in the shoulder season. It's one of the cheapest transatlantic routes from any U.S. city.
For Caribbean escapes, JetBlue dominates with nonstops to San Juan, Cancún, Aruba, St. Maarten, and Bermuda. These routes get expensive in winter when New Englanders flee the cold, but drop sharply in May and September.
Boston's biggest fare disadvantage is the New York comparison. On some routes, especially to Asia, it's worth checking JFK/EWR fares plus a $15 bus ticket on the Chinatown bus or a $60 Amtrak. The fare difference can be $200+ on transpacific routes where Boston has no nonstop service.
