Cheap flights from London to Sioux Falls

Two things move the prices here: the holiday calendar in the United Kingdom and the seasons in the USA. Christmas and the school breaks are the obvious pressure points, which is why July sits in the calendar next to the winter months — it is the destination's summer. December comes out cheapest, and the table also covers October, November, January and February, so the whole stretch from mid-autumn to late winter can be compared at a glance. If your dates are flexible, try nudging a departure away from Friday or Sunday before you settle; on a connecting route, a small shift in dates often changes the total more than a change of airline.

Not one low-cost brand appears on the list for this route: the ten names — Brussels Airlines, Lufthansa, Lufthansa City Airlines, United Airlines, British Airways, American Airlines, Aer Lingus, BA CityFlyer, Virgin Atlantic and Delta Air Lines — are full-service operators, so what separates them is not the cabin product but the connection. Compare where the change of planes happens, how long the layover runs and whether both legs sit on a single ticket before you look at anything else. Then read the fare conditions: full-service airlines also sell light booking classes, and a fare without a checked bag loses its appeal once you price the bag on its own.

Treat an evening arrival as the default: with a transatlantic leg and a connection behind you, you are likelier to walk out of Sioux Falls Regional after dark than in bright daylight. The airport is the city's only one and sits a short drive from the centre, so the way in is simple — a taxi or ride-hail covers it, and car hire desks sit by the terminal. What a late arrival changes is your margin for error: check the car rental counters' hours if you need a car, and have your first night's transport and address settled before you take off, because a small airport offers fewer fallbacks once the desks shut.

Country facts: Wikidata

• Every itinerary here includes a connection, so compare layover and total journey time before the fare itself.
• If your two legs are separate tickets, leave a wide buffer — the second airline need not rebook you when the first runs late.
• Check what the fare includes: even full-service carriers sell classes without a checked bag, and the long leg is where that hurts.
• Confirm which London airport you leave from — City, Gatwick, Heathrow, Luton and Stansted all appear on this page.
• Sort out US documents early: British passport holders normally need an ESTA, and a visa takes longer.
• December is the cheapest month here, but Christmas and school holidays price differently, so compare the whole grid.
