Cheap flights from London to Hartford

November is the cheapest month on this route, and the fares for it are usually the lowest on the price calendar. Autumn and late winter are quieter than the summer rush, when transatlantic seats fill up fast; September, October, January, April and May sit in the middle, and December is the one to plan around, since the winter holidays push demand up. Midweek departures from Heathrow or Gatwick tend to be calmer and cheaper than Friday and Sunday flights, and an early start leaves more room if a connection slips. Book well ahead for summer and December, and later for November, when demand drops.

There are no nonstop flights from London to Hartford, so every itinerary pairs a transatlantic carrier with a short connecting hop. American Airlines and United Airlines are the names you will see most on the US side, while Virgin Atlantic, Aer Lingus, Air France, KLM Royal Dutch Airlines, Lufthansa, Lufthansa City Airlines, TAP Portugal and Helvetic Airways appear on the European legs. These are full-service airlines rather than low-cost carriers, so what differs is mostly the fare type: a hand-baggage ticket on a short leg may not include a checked bag, while a transatlantic fare usually does. Compare what is included, not just the fare.

Bradley International is the airport for Hartford, and it is the only one serving the city, so every London itinerary ends there. It sits outside the city rather than beside it, which means a transfer into downtown Hartford rather than a walk, and the usual choices are a taxi, a ride share, a hotel shuttle or a rental car picked up at the terminal. Allow time for US immigration and customs on arrival, since the first US airport you touch is where you clear them, and that queue can be long on a busy afternoon. If your connection lands late, keep the number for your onward transport handy.

Country facts: Wikidata

• Decide which London airport you leave from — Heathrow, Gatwick, Luton, Stansted or London City — before you compare fares.
• Check whether the connection is on one ticket or two; separate tickets mean you carry the risk of a missed onward flight.
• Read the baggage rules for every leg, since a transatlantic fare and a short connecting hop can differ.
• Confirm your passport and US entry authorisation are valid before you pay, as the airline checks them at the gate.
• Compare November fares with September and January on the price calendar before you fix your dates.
• Leave a generous gap at the connecting airport, as US-bound legs take longer to clear than European ones.
