Which airlines fly direct from London to Belfast?

You’ll find plenty of direct flights from London to Belfast, most commonly operated by three airlines. The first are the regular British Airways flights that will take about an hour and a half to get you there. Another major carrier offering direct flights on this route is Aer Lingus, which takes roughly the same amount of time. For cheap flights from London to Belfast, you can book on easyJet through momondo, which has only a few minutes longer duration. There are also the odd one-stop flights between these two British cities. One is operated by KLM and flies first to Amsterdam Schiphol Airport (AMS). The other departs on British Airways then switches to Loganair at Inverness. These don’t offer any extra value for the additional flying time – in fact, they tend to cost a lot more than the direct flights, so our advice would be to fly direct. The exceptions are the really cheap flights from Stansted Airport (STN) on Ryanair, but at the cost of travel time, as they fly via Poland. What is the best way to get in and out of airports in London and Belfast? Most London to Belfast flights depart from either Heathrow Airport (LHR) or Gatwick Airport (LGW) and land at George Best Belfast City Airport (BHD). The long flight from Stansted lands at Belfast International Airport (BFS). A quick way from central London to Heathrow is to use the Heathrow Express, departing from Paddington Station every 15 minutes or so. Using the Underground, you can take the Piccadilly Line from Leicester Square Station; otherwise, catch the 170, C10 or 44 buses from Victoria Coach Station. The Southern Service train from Victoria Station will take you to Gatwick, and you can reach Stansted on the Express buses and trains from London Liverpool Station. From Belfast City Airport, you can reach the city centre in about seven minutes on the Line 1 train, or catch the Line 600 bus that takes about nine minutes. The Line 600 subway takes roughly 10 minutes. A taxi or hire car will get you there in just over five minutes. From Belfast International Airport, take the Line 300 bus or the 109a bus linking to the Line 3 train. What are the benefits of the different airports in London and Belfast? Heathrow and Gatwick are on the outskirts of London, in different directions. If you’re travelling from central London, Heathrow is your closer option, lying to the west. If you’re coming up from southern England, though, Gatwick will make a better choice, as it’s near Crawley, on the way into the city. You’ll be able to get return and one-way flights from London to Belfast from both airports. They also both have a wide variety of shops, coffee shops, bars, restaurants and fast food outlets and are sophisticated modern airports, with very good accessibility features. Belfast City Airport is designed for domestic travel only and has a few eateries, coffee shops and a fair sized duty-free area. It’s advantage is that it’s so close to the city centre. Belfast International Airport is quite a small airport, with a really nice Causeway Lounge, a selection of shops, baby change facilities and a quiet room.

Which cities can you reach easily once you arrive at Belfast airports?

As both airports serve Belfast city, they both offer similar access to the surrounding cities and towns, like Lisburn to the south-west and Bangor in the north-west on the coast. To get to Lisburn, you can take the Line 1 train, which will take about 45 minutes, or Subway Line 600, switching to the Line 1 train; this will take about an hour. You can get there in about 20 minutes by taxi or in a hire car. Bangor is even closer; the Line 1 train will take just under half an hour to get there, with a bus on the 502a Line taking between 35 and 45 minutes. By road, it will once again take under 20 minutes.
