Edinburgh has become a surprise battleground for US carriers, and new Department of Transportation figures suggest JetBlue may be losing the fight on one of its two Scottish routes. The airline flies seasonal nonstops to Edinburgh from both New York JFK and Boston, but the numbers for summer 2026 couldn't be more different.
On the JFK route, JetBlue never cracked a 70% average load factor in any month from April through July. May came in at 66.2%, June at 67.6%, and July at 69.1% — an average of just 67.5% across the busiest travel season of the year. That's a weak result for a corridor linking New York with one of Europe's most popular city-break destinations, and it's made tougher by competition: Delta and American both fly the same route. JetBlue has pencilled in 178 rotations from late April to late October this year and currently plans to return next summer, but nothing is confirmed. The airline didn't respond to a request for comment.
Boston tells a different story. Despite a slow start in April (69.35%), the route settled above 80% occupancy for May, June and July — 82.4%, 82% and 82.6% respectively. With only Delta as a rival, and that rival starting its season later, JetBlue has more breathing room on its 191 scheduled rotations.
Aircraft choice adds a wrinkle. Both Edinburgh routes are flown with the A321neo, which has more seats than the smaller A321LR, so the airline needs an 86.25% load factor here to match what it would fill on an LR. The flip side is a smaller Mint business cabin — and premium demand may ultimately decide whether Edinburgh stays on the map for JetBlue.
There's precedent for a cull. JetBlue has already dropped two European routes from JFK: London Gatwick (cut in December 2024) and Amsterdam (reported cut a year later). It still serves Heathrow from JFK, and keeps flying from Boston to both Gatwick and Amsterdam.
For travellers, the practical takeaway is straightforward: if you're planning a New York-Edinburgh nonstop, book sooner rather than later, and expect fares on Delta and American to firm up if JetBlue exits. Boston-based flyers are on safer ground, with consistently full planes suggesting that route is secure. Either way, Scotland's capital remains easy to reach nonstop from the East Coast — it's just a question of which airline you'll be flying with next summer.
