Planning a trip to London often starts with one important decision that many travellers don't think about until it's too late: which airport should you fly into?
London is served by several international airports, but two stand out above the rest—Heathrow and Gatwick. Both welcome millions of passengers every year, offer flights to destinations across the globe, and provide good transport links into central London. On the surface, they might seem quite similar. In reality, they offer very different travel experiences.
The airport you choose can affect everything from your airfare and journey time to your transport costs and even how relaxed you feel when you arrive. If you're visiting London for the first time, flying with a particular airline, or simply trying to keep your travel budget under control, it's worth understanding the differences before you book.
The good news is that there isn't a single "best" airport. The right choice depends on your destination, your airline, your budget, and what matters most to you. In this guide, I'll compare Heathrow and Gatwick across the areas that travellers care about most, helping you decide which airport is the better fit for your journey.

Although both airports are well connected, each has its own strengths. Let's take a closer look.
Location and Getting Around
One of the first differences you'll notice is where each airport sits in relation to London.
Heathrow is located to the west of the city and is much closer to central London. This makes it particularly convenient if you're staying in areas such as Paddington, Kensington, Westminster or the West End. Depending on where you're headed, getting into the city can be surprisingly quick.
Gatwick, on the other hand, lies south of London in West Sussex. While it's further away, don't let that put you off. Modern rail services mean you can still reach central London in around half an hour, making it an easy journey for most visitors.
Flight Destinations and Airline Choices
Perhaps the biggest difference between Heathrow and Gatwick is the type of flights they offer.
Heathrow: London's Global Hub
Heathrow is the UK's busiest airport and one of the world's largest international aviation hubs. If you're flying long-haul, there's a good chance you'll arrive here. The airport serves hundreds of destinations across Europe, North America, Asia, Africa, the Middle East and South America. It also handles a huge number of connecting passengers every day.
You'll find many of the world's leading full-service airlines operating from Heathrow, including flagship carriers from countries around the globe. If you're flying in premium economy, business class or first class, Heathrow generally offers the widest choice. Because so many international routes pass through Heathrow, it's also one of the easiest airports for connecting flights. If you're travelling onward to another destination, you'll usually have more options and more frequent departures.
Gatwick: A Favourite for Leisure Travel
Gatwick has a slightly different focus. It's particularly popular with holidaymakers thanks to its excellent selection of European and Mediterranean routes. During the summer months, the airport becomes one of the busiest gateways for travellers heading to Spain, Portugal, Greece, Italy and other popular sunshine destinations.
Budget airlines have a strong presence at Gatwick, which often means lower fares if you're travelling within Europe. That doesn't mean Gatwick only offers short-haul flights. There are also plenty of long-haul services to North America, the Caribbean, Asia and the Middle East, although the selection isn't as extensive as Heathrow's.
If you're simply looking for the cheapest flight rather than the largest choice of destinations, it's worth checking fares from both airports. Sometimes the difference can be surprisingly significant.
Which Airport Is Better for International Flights?
If your journey involves travelling between continents, Heathrow usually comes out on top. With its enormous route network, multiple daily departures and excellent airline partnerships, Heathrow gives travellers far more flexibility. Miss a flight or need to change your plans, and there's often another departure later the same day.
For business travellers, frequent flyers and anyone making international connections, that's a huge advantage. Gatwick still offers a respectable range of long-haul destinations, but flights are generally less frequent. Depending on where you're travelling, you may have fewer airline choices and longer waits if plans change.
Which Airport Is Better for European Holidays?
This is where Gatwick shines. Many of Europe's biggest low-cost airlines operate extensive networks from Gatwick, making it one of the best airports for affordable holidays. Whether you're planning a weekend city break, a beach holiday or a skiing trip, Gatwick often offers competitive prices and convenient flight times.
For many UK and European travellers, Gatwick has become the airport of choice simply because it offers excellent value without sacrificing convenience.
• If your priority is global connectivity, premium airlines and international transfers, Heathrow is difficult to beat.
• If you're searching for affordable European flights and a slightly less overwhelming airport experience, Gatwick is an excellent alternative.
Of course, choosing an airport isn't just about where the plane lands. The journey into London, the ease of navigating the terminals and the overall travel experience can make just as much difference. In the next section, we'll compare transport options, terminal layouts, facilities and what it's actually like to pass through each airport.
