Boston to London is New England's premier transatlantic route, with five airlines operating 6–7 daily nonstop flights from Logan International to Heathrow. British Airways leads with 2 daily departures, while Delta, Virgin Atlantic, American Airlines, and JetBlue each add daily service. JetBlue's Mint Suite on the A321LR is a standout — offering lie-flat business class at a fraction of legacy carrier prices. With fierce competition on this route, Camli's consolidator network consistently surfaces fares that mainstream booking sites miss, especially on premium cabins.

JetBlue's Mint Suite on the A321LR offers a fully enclosed lie-flat seat with closing door, 17-inch screen, and fresh food — often for $1,000–1,500 RT when deals appear. That's 50–70% less than BA Club World or Delta One on the same route. Set fare alerts and book when Mint drops below $1,200 RT.
Boston Logan is one of the closest major airports to a city center in the US — just 3 miles from downtown. The Blue Line subway connects directly, and a taxi/rideshare takes 10–15 minutes outside rush hour. This means less travel time and later departure from your hotel.
Aer Lingus via Dublin offers US preclearance on return flights — you clear US customs and immigration in Dublin before boarding, arriving at BOS as a domestic passenger. This saves 30–60 minutes at Logan and fares are often $60–100 cheaper than nonstop.
Delta and Virgin Atlantic are joint venture partners on BOS–LHR. You can earn Delta SkyMiles on either carrier. If schedule or price favors one over the other, your loyalty status and miles still apply. Combined, they offer 2–3 daily nonstops.
BA arrives at Terminal 5 (home base), Delta and VS at Terminal 3, AA at Terminal 3, JetBlue at Terminal 2. The Elizabeth Line (Crossrail) reaches central London in ~30 minutes from Heathrow. The Heathrow Express to Paddington takes 15 minutes.

The British Museum, Tate Modern, National Gallery, Natural History Museum, and V&A are all free to enter. London has more free museums than any other city in the world.
