Cheap Flights to Boston

JetBlue vs. Delta keeps Logan one of the Northeast's best-value airports

Flight Deals to Boston

Boston Logan (BOS) is a fierce battleground between JetBlue, which calls it a focus city, and Delta, which runs a competing hub. That rivalry — plus strong service from American, United, and budget carriers — keeps fares sharp on domestic and transatlantic routes alike. As one of the Northeast's busiest airports, Logan sees frequent sales, and the JetBlue-Delta fare wars regularly produce deals across the country and to Europe.

Best Time to Fly to Boston

January through March (after the holidays) offers the lowest fares. Avoid summer, fall foliage season, and college move-in weekends in late August.

Frequently Asked Questions

When are flights to Boston cheapest?

January through March is the cheapest window, with roundtrip fares from the Midwest and Southeast dropping to $110-170. New England winters suppress leisure demand, so prices fall. Summer and fall foliage season (late September-October) are the most expensive times to visit.

Which airlines fly cheapest to Boston?

JetBlue, with its Logan focus city, and Delta, with a competing hub, wage constant fare wars that keep prices low. American and United add competition, while Spirit offers budget fares on select routes. The JetBlue-Delta rivalry makes Boston a reliable source of deals.

Is Boston a good airport for cheap flights to Europe?

Yes. Logan is one of the better East Coast gateways to Europe, with strong transatlantic competition from Delta, JetBlue, and European carriers. Roundtrip fares to London, Dublin, and other hubs regularly drop to $400-550 during sales, especially in the winter off-season.
