Cheap Flights from Boston Logan 2026

Boston Logan is a smaller, less chaotic airport than JFK, LaGuardia, or Newark — and for certain routes it's genuinely cheaper to fly from BOS than from New York. The main reason: Aer Lingus, Norwegian, and TAP Air Portugal all use Boston as a key transatlantic hub, and their competition with Delta, JetBlue, and American keeps transatlantic fares from BOS lower than you might expect for a non-hub city.

JetBlue has a major focus city at BOS and operates the highest frequency of any carrier on Boston's key domestic routes — JFK, Fort Lauderdale, Orlando, San Juan, and many others. JetBlue's BOS–FLL route is one of the most price-competitive domestic routes in the Northeast — Spirit and Frontier also compete, so the floor price is low year-round.

Logan itself is 10 minutes from downtown Boston by Silver Line bus (free from Terminal E on arrival) or Blue Line (from Airport station, a short shuttle ride). It's one of the easiest major US airports to access from a city centre — a meaningful advantage over JFK or Newark for city-centre travellers.

Boston (BOS) to Fort Lauderdale (FLL): JetBlue, Spirit, and Frontier all compete. JetBlue around $110–145 one-way for summer. Spirit under $90 one-way without bags. Fort Lauderdale is effectively cheaper Miami — 30 minutes from South Beach, better cruise port, and a beach in its own right. Strong for families and budget travellers.

Boston (BOS) to Dublin (DUB) — Aer Lingus: Aer Lingus's transatlantic operation is genuinely strong on this route. Current summer one-way fares: $390–520. Aer Lingus offers US Preclearance from Dublin — you clear US customs and immigration at Dublin Airport on departure, landing in the US as a domestic arrival. It's a significant time saving if you're transiting through Dublin on the return.

Boston (BOS) to Reykjavik (KEF) — Icelandair: Icelandair operates BOS–KEF with competitive summer fares: $420–580 return. Iceland as a destination from Boston is excellent — 5.5 hours, extraordinary scenery, and the free stopover policy means you can see Iceland on the way to or from Europe at no extra fare cost.

Boston (BOS) to San Juan, Puerto Rico (SJU): JetBlue around $160–210 one-way for summer. JetBlue is the dominant carrier on this route from BOS — frequency is high, fares are competitive, and the 3.5-hour flight is manageable. San Juan is popular with New England travellers for the warm weather, beaches, and no passport requirement for US citizens.

Boston travellers sometimes overlook routes that save real money compared to New York pricing. BOS to Chicago (ORD) on American or JetBlue is often $30–50 cheaper than JFK–ORD because there are fewer business travellers on the route and less pricing pressure. JetBlue from BOS to Chicago Midway doesn't exist, but the BOS–ORD market has enough competition to keep prices honest.

BOS to Miami (MIA) has American, JetBlue, and Frontier competing. Summer fares around $140–180 one-way. The BOS–MIA route is popular with snowbirds in reverse in summer — Miami residents flying to Boston to escape the heat — which keeps competition strong.

BOS to Los Angeles (LAX) is around $220–300 one-way for summer on JetBlue or American. JetBlue's Mint (business class) on BOS–LAX is one of the best domestic business products in the US and sometimes available at $600–800 one-way — legitimately excellent value for a 5.5-hour transcontinental.

JetBlue TrueBlue points are disproportionately valuable from BOS. JetBlue has high frequency from Boston, which means award availability is better from BOS than from smaller JetBlue cities. If you have TrueBlue points, BOS-to-Caribbean and BOS-to-Florida redemptions are frequently available and the point costs are lower than transatlantic awards.

Compare Aer Lingus to BA and Virgin for transatlantic. For Boston to London, Aer Lingus via Dublin (with US Preclearance at Dublin on the return) is frequently the best combination of price and convenience. BA flies BOS–LHR direct but often at $40–80 more per segment. Run the comparison on your specific dates — the Preclearance benefit alone is worth something.

Fenway-area departures: drive vs cab vs T. Logan is deceptively accessible. The Silver Line from South Station connects to all Logan terminals. From Fenway, a $22 Uber to Logan is often the right call versus the T (20 minutes plus shuttle). From North End or Seaport, the Silver Line from Silver Line Way is walkable and free from Terminal E. Know your options before budgeting for transport.

Book summer BOS departures before Memorial Day. JetBlue runs yield management from BOS very actively. The week after Memorial Day historically sees a fare jump on BOS transatlantic and Caribbean routes as demand crystallises for June–August. Book before May 25 for the best summer pricing.
