Cheap flights from London to Indianapolis

April comes out cheapest in the fares we track, and the price calendar covers September through June, which makes late spring and early summer the most comfortable window for this route. Midweek departures usually cost less than Friday or Sunday flights, so try Tuesday or Wednesday if your plans allow. Fares climb around Thanksgiving and the December holidays, when everyone is flying to see family, and stay high through the run-up to Christmas. Book a few months ahead for spring travel. July and August are not in the calendar, so check those separately if you want to fly in high summer.

Nobody flies London to Indianapolis nonstop, so every itinerary here is a connection, typically through a European hub or a Canadian gateway. Lufthansa, Lufthansa City Airlines, Brussels Airlines, TAP Portugal, Finnair, Air Canada and BA CityFlyer are full-service, which normally means a checked bag and meals are part of the ticket. Air Baltic and Helvetic Airways sit somewhere in between, and Portug turns up on some itineraries too — on those lighter fares, hand baggage may be all you get unless you pay for more. BA CityFlyer leaves from London City, which changes both your departure airport and your connection.

Indianapolis International is the city's airport, and it sits outside downtown rather than in it, so build in time for the transfer once you land. A taxi or a rideshare is the simple way in, and some hotels run their own shuttle, so ask before you book the room. If you plan to drive, sort the car out before you fly rather than after you land. Your first stop on US soil is where you clear immigration and customs, so leave a generous connection there, and if you carry on to another city afterwards, expect to collect and re-check your bags.

Country facts: Wikidata

• Check which London airport your fare leaves from, because London City, Gatwick, Heathrow, Luton and Stansted are nowhere near each other.
• Confirm whether your connection is on one ticket or two, since a missed self-transfer is your problem, not the airline's.
• Read the baggage rules on the lighter carriers, where a hand-baggage-only fare is common.
• Make sure your passport and any US entry paperwork are in order well before departure.
• Leave a long connection at your first US airport, because that is where you clear immigration.
• Book April if you are following the price calendar, and expect higher fares around Thanksgiving and the winter holidays.
