How long is the flight from Miami to London?
A non-stop flight from Miami to London-Heathrow takes about 8 hours 45 minutes eastbound, riding the jet stream, with the fastest scheduled times slightly quicker. The return runs longer against headwinds, typically around 9 hours 30 minutes to 10 hours.
With three carriers on the route, you get multiple departures across the day — overnight flights that land in London the following morning are the classic choice for maximizing time on the ground. A one-stop itinerary, often cheaper or the only thing available on peak dates, brings total travel time to around 11–14 hours, usually via another US hub or a European gateway.
Which airlines fly the route (and which are cheapest)
- British Airways — the long-standing operator into Heathrow, with daily flights and the broadest schedule in alliance with American. Full service, including checked baggage on standard fares.
- American Airlines — flies non-stop from its Miami hub into Heathrow, codesharing closely with BA. Frequently competitive on price, especially on its own metal.
- Virgin Atlantic — the third non-stop operator, a strong low-fare competitor on this corridor and often the one pushing the price floor down.
- Connecting carriers and Gatwick options — one-stop fares through other hubs, and occasional service into Gatwick, can undercut the Heathrow non-stops in low season.
Because BA and AA share revenue on this route under their joint business agreement, Virgin Atlantic is often the carrier that shakes up the price — so always include it.

Airports: Miami (MIA) and London-Heathrow (LHR)
Miami International (MIA)
South Florida’s main international gateway and an American Airlines hub. MIA is large — allow plenty of time, as security and immigration lines can be long at peak hours. The airport is close to downtown Miami; Metrorail (Orange Line) and ride-share serve it directly. Confirm your terminal before you travel.
London-Heathrow (LHR)
Where the non-stops from Miami land. The Elizabeth line, Heathrow Express and the Piccadilly line all reach central London — the Express is fastest (about 15 minutes to Paddington), while the Elizabeth line and Underground are the best-value options. Allow time for UK border controls on arrival, which can be slow at peak.
When is the cheapest time to fly to London?
- January and February — the cheapest months, as transatlantic demand drops after the holidays.
- September, October and November — the next-best window: London is mild, crowds thin, and fares fall from summer highs.
- March–May (outside Easter) — shoulder season with reasonable prices and pleasant weather.
When to avoid on price: June through August (peak European summer), late December, and Easter, when transatlantic demand peaks. If summer is your only option, book two to three months ahead. Tuesday and Wednesday departures are usually the cheapest days. Flying elsewhere from Miami? See our Miami to Paris and Miami to Madrid guides.
