The route in one look
Heathrow to Dubai runs to Dubai International (DXB), the big airport close to the city, and not to Al Maktoum International (DWC) out at Dubai World Central. Every Heathrow service uses DXB, which makes this one long-haul route where the far-end airport needs no thought at all. Emirates arrives at DXB Terminal 3, the building it occupies on its own.
The distance is about 3,414 miles, or 5,494 km great circle. Eastbound the flight is blocked at roughly 7 hours 50 minutes to 8 hours; westbound to London it runs about 7 hours 45 minutes to 7 hours 50 minutes. Unusually for a long-haul route, the two directions are almost the same, and the eastbound leg is currently the marginally longer of the two rather than the shorter one you might expect. In pure flying time that is not much more than a transatlantic crossing, but the four-hour time difference in summer, and the fact that so many services run overnight, makes it feel like a bigger trip.
The route works in both directions with dense service each way. Eastbound flights leave London through the day and overnight, with the overnight departures landing in Dubai in the morning; westbound flights include both a morning arrival into Heathrow and daytime options that get you home in the afternoon. That choice matters more on this route than most, because a Dubai trip is very often a connection rather than a destination.
Who flies it
This is normally a three-carrier route. As of 28 July 2026 it is a one-carrier route, and the reason is worth understanding before you book.
- Emirates flies from Terminal 3 and is currently the only airline on the route, with several departures a day. This is the flagship route of its network and it has long been the corridor Emirates puts its largest aircraft on, in a four-class layout with first class and premium economy.
- British Airways normally flies from its Terminal 5 base into DXB Terminal 1. It suspended Dubai along with six other Middle East routes from Heathrow when airspace closures swept the Gulf, and is scheduled to resume on 1 August 2026, with a second daily service planned from 16 October 2026.
- Royal Brunei Airlines normally serves Dubai from Terminal 4 as a stop on its London to Bandar Seri Begawan service, which makes the London to Dubai leg bookable in its own right. Since March 2026 it has flown non-stop to Bandar Seri Begawan instead, skipping Dubai entirely, an arrangement currently extended into September 2026.
The practical consequence: if you are reading an older guide, or a comparison site that has not caught up, you may be shown a choice of three airlines on this route that does not currently exist. Check the live departures board for what is genuinely flying on your date, and treat any Middle East booking made now as worth re-checking closer to travel. The airlines at Heathrow page has the full terminal mapping.
What none of these carriers do is compete on connection quality in the same way. Emirates is built around funnelling Heathrow passengers onward through Dubai to Asia, Australia and East Africa, and its schedule is timed for it. British Airways treats Dubai as an end point. So even when all three are flying, Emirates is usually the only sensible choice if Dubai is your connection rather than your destination.
When to fly
Dubai has the clearest seasonal split of any Heathrow long-haul destination, and unusually it works in your favour: the cheap season is cheap for a reason you can simply decide to accept or avoid.
November to March is the good weather and the peak fares, with the Christmas and New Year period the most expensive stretch of the year. June to September is Dubai’s summer, and it is genuinely punishing outdoors, with temperatures that make walking anywhere impractical for much of the day. Fares drop accordingly, and if your trip is mostly indoors, a summer visit is the best value on the route. April, May and October are the shoulder months and the sensible compromise: warm rather than brutal, and priced between the two.
Ramadan moves through the calendar each year and changes the experience noticeably, with restricted daytime eating and drinking in public and different opening hours across the city. It is worth checking the dates for your travel year rather than assuming, because it affects what a leisure trip looks like more than the temperature does.
On the connection question: a Dubai stop is one of the standard ways to reach destinations with no Heathrow non-stop, and for much of the Pacific it is the routeing rather than a compromise. Emirates prices these itineraries aggressively and frequently undercuts a non-stop where one exists. The cost is the extra hours and a connection that can land in the middle of the night. If you are travelling with children or on a tight schedule, price the non-stop properly before assuming the Dubai routeing wins, and bear in mind that the same regional disruption has reshaped schedules across the Gulf.
At the airport
Today, Dubai flights leave from Terminal 3, because Emirates is the only airline on the route. When British Airways resumes it will fly from Terminal 5, and Royal Brunei uses Terminal 4 when its Dubai routeing is running. Those buildings are a long way apart, so check the airline on your booking rather than assuming, and use the which terminal page if it is unclear.
Terminal 4 deserves a specific warning if a Royal Brunei booking puts you there. It sits away from the central terminal area, it is the most awkward of the four to reach, and its multi-storey car park closed in June 2026 as part of a redevelopment programme, with parking moved to Zone A of the Terminal 4 Park & Ride. If you are driving, read the Terminal 4 parking page before you set off rather than after.
Allow around three hours for a long-haul departure and more in the winter peak. Emirates passengers in the premium cabins have the Emirates Lounge at Terminal 3, which is reported to be the only lounge at Heathrow that boards directly to the aircraft rather than sending you back out to a gate. If you are connecting onto a Dubai flight from another Heathrow arrival, the connecting flights page covers minimum connection times and what a terminal change involves.
Who it suits, honestly
Right now the honest answer is that there is no choice to make. Emirates is the only airline flying Heathrow to Dubai, so the decision is which departure time suits you and which cabin you want, not which carrier. That is worth knowing before you spend an evening comparing.
Emirates is the right default anyway if Dubai is a connection, or if you are travelling in a premium cabin, where the Terminal 3 lounge is a real advantage on a long day. Its whole Heathrow operation is built around onward connections through Dubai.
Wait for British Airways if you collect Avios and your dates are flexible past 1 August 2026. On a straight Dubai return it is a genuine like-for-like rival rather than a fallback, and Terminal 5 is the easier departure for many people. Book it only once you can see it in the schedule, not on the strength of the announced resumption date.
Do not book a Dubai connection on price alone if you are travelling with young children or on a trip where a lost night matters. The onward connections often sit in the small hours, and the saving over a non-stop can evaporate once you have paid for a day hotel or arrived somewhere unable to function.
Above all, check the live board before you plan around a carrier. This route has changed shape twice in 2026, and it will change again when British Airways returns.
