The Complete Guide to Gatwick Airport: Everything You Need to Know Before You Fly

Introduction to Gatwick Airport

London Gatwick is the United Kingdom's second-busiest airport and the principal gateway to London and the South East for millions of travellers each year. It is a genuinely major international airport — but it operates quite differently from Heathrow, and travellers who assume the two are interchangeable often discover the difference at the worst possible moment.

Gatwick sits near Crawley in West Sussex, roughly 28 to 30 miles south of central London. That distance matters. Heathrow is on the western edge of the city and connected to the Underground network. Gatwick is genuinely outside London, connected by mainline rail rather than by Tube, and reaching it takes real planning rather than a casual half-hour.

The airport is important to the region for reasons beyond passenger numbers. It is the main base for a large share of the UK's short-haul leisure flying, a growing long-haul operation, and the practical choice for anyone in Sussex, Surrey, Kent or south London for whom crossing the capital to reach Heathrow makes no sense.

Who flies from Gatwick

Gatwick's passenger mix skews towards leisure travel — holidaymakers, families, and people visiting friends and relatives across Europe. It is a major base for low-cost carriers, which shapes everything from the check-in experience to how strictly baggage rules are enforced. But it also handles a substantial long-haul operation and a meaningful share of business travel, particularly from the South East.

Gatwick and Heathrow: the differences that matter

Distance and connection. Heathrow is around 15 miles west of central London with three rail options including the Underground. Gatwick is roughly double that distance to the south, served by mainline trains only.

The traffic mix. Heathrow is the long-haul network hub where the major alliances concentrate. Gatwick leans towards European short-haul and leisure, with a growing long-haul presence.

Terminals. Heathrow has four terminals scattered across a large site. Gatwick has two — North and South — which sounds simpler, and mostly is, provided you go to the right one.

Where you arrive in London. Trains from Heathrow bring you into Paddington or onto the Underground network. Trains from Gatwick bring you into Victoria, London Bridge, or the Thameslink stations through the middle of the city. That single fact should shape your transport choice more than anything else.

They are not interchangeable. If you have booked a connection between Gatwick and Heathrow, you have booked a substantial cross-London journey between two separate airports. Treat it as such.

Why the layout matters

Gatwick's two terminals are separate buildings connected by a transit system. The railway station is at one of them. Get the terminal right and Gatwick is one of the easier major airports to use. Get it wrong and you are moving between buildings under time pressure with your luggage. Almost everything else in this guide follows from that.

What is the best way to get to and from Gatwick Airport?

The best option depends on your destination, budget, luggage and timing. The Gatwick Express is the fastest scheduled service to London Victoria. Thameslink costs less and runs through the middle of London to London Bridge, Farringdon and St Pancras, which suits many travellers better. Southern services offer a middle option to Victoria and London Bridge. Coaches are the cheapest but the slowest. A taxi or pre-booked private transfer is usually the most practical choice for families, heavy luggage, late-night arrivals, or destinations away from a station.

Fares and timetables change, so confirm current information with the operator before you travel.

Airline and terminal information changes. Confirm your terminal with your airline and with gatwickairport.com before travelling — the list above describes the general picture, not your specific flight.

Understanding Gatwick Airport's Terminals

Gatwick has two passenger terminals, North and South. They are separate buildings, connected by a transit system, and they are not walkable from one another in any practical sense.

Before the detail, the warning that governs this entire section: airlines move between terminals. Allocations change, sometimes at relatively short notice, and an airline may operate from one terminal for some routes and the other for others. Your booking confirmation and your airline's own website are the authoritative sources for your specific flight. Everything below describes the general character of each building.

North Terminal

Airlines. The North Terminal handles a large share of Gatwick's short-haul low-cost operation, along with a number of other carriers. If you are flying with a major low-cost airline from Gatwick, North is the more likely starting point — but confirm it.

Check-in and departures. A large check-in hall with extensive self-service bag drop, reflecting the airlines that operate here. Self-service is the norm rather than the exception, so allow time to work out the system if you are not used to it. Bag drop deadlines with low-cost carriers tend to be enforced strictly.

Security. A substantial security operation. Queues vary considerably with the time of day and the season — early morning departure banks in the summer are the pressure point.

Departure lounge. A large open departure area with the shopping and dining concentrated in the middle and gates leading off from it. Some gates require a walk of a good ten to fifteen minutes, and a few require a shuttle, so check the screens rather than settling in somewhere comfortable.

Shops and restaurants. A full range of duty-free, fashion, technology and gift retail, plus restaurants, cafés and bars.

Lounges. Independent pay-to-enter lounges, plus airline lounge provision.

Arrivals. Baggage reclaim, then into the arrivals hall with its meeting area and onward transport signage.

Accessibility. Step-free throughout, with lifts, accessible toilets and assistance points.

Transport connections. The North Terminal does not have its own railway station. Rail passengers arrive at Gatwick Airport station at the South Terminal and use the inter-terminal transit. Road access, coach stops, car parks and taxi ranks all serve the North Terminal directly.

Worth knowing. The rail connection is the single most important practical point. If you are flying from the North Terminal and arriving by train, add the transit journey to your plan — it is short, but it is not zero, and it is one more thing to go wrong when you are late.

South Terminal

Airlines. A mix of long-haul operators, British Airways, and a range of short-haul and charter carriers. As with the North Terminal, confirm rather than assume.

Check-in and departures. A check-in hall with a mix of staffed desks and self-service bag drop, reflecting a broader spread of airline types.

Security. As with the North Terminal, queue times vary with the season and time of day.

Departure lounge. A large departure area with retail and dining, and gates leading off. Some gates involve a significant walk.

Shops and restaurants. Comparable in range to the North Terminal, though the specific outlets differ. If you have a favourite, it may not be in both.

Lounges. Independent lounges plus airline provision.

Arrivals. Baggage reclaim, arrivals hall, and direct access to the railway station.

Accessibility. Step-free throughout, with lifts and assistance points.

Transport connections. The South Terminal is directly connected to Gatwick Airport railway station — the reason it matters more than any other single fact about Gatwick's layout. Coach services, car parks and taxi ranks also serve the terminal.

Worth knowing. If your flight is from the South Terminal and you are travelling by rail, your journey is genuinely straightforward: train to Gatwick Airport station, walk into the terminal. This is the easiest arrival experience at either London airport.

The differences that actually matter

Both terminals offer broadly comparable facilities. The differences that affect your journey are:

The South Terminal has the railway station. The North Terminal does not.
The terminals have different airlines, and the split can change.
Retail and dining outlets differ, though the overall standard is similar.
They are separate buildings. Arriving at the wrong one is a real journey, not a short walk.

Check your terminal before you leave home. It costs two minutes and it is the most consequential piece of preparation you can do for a Gatwick departure.

How to Find Your Gatwick Terminal

Check in this order:

Your booking confirmation. Usually states the terminal, but reflects the position at the time of booking, which may have been months ago.
Your boarding pass. More current, generated closer to departure.
Your airline's website. The most reliable source, since the airline knows where it is operating from.
Your airline's mobile app. Useful for push notifications about changes.
gatwickairport.com. Publishes live departure information by flight number, including terminal.
Airport information screens. Useful once you have arrived, but a poor plan A.

Check the day before you fly, and again on the morning of travel.

If you arrive at the wrong terminal

Do not panic, but do move immediately. Head straight for the inter-terminal transit and go. The journey is short, and passengers make this correction every day without missing flights.

Where it becomes serious is if you are already close to your bag drop deadline. In that case, go to the transit first and call your airline while you travel rather than queuing at a desk in the wrong building. If you are very tight, tell staff at the transit or in the terminal — they deal with this constantly and can advise.

The lesson for next time is simply to check before leaving home.

Travelling Between Gatwick's North and South Terminals

Gatwick operates a free automated transit service connecting the two terminals, running frequently throughout the day with a journey time of only a few minutes. There is no ticket and no charge.

Arrangements at Gatwick have been subject to change during periods of redevelopment, with bus transfers operating at times in place of or alongside the automated service. Check the current arrangement on gatwickairport.com before you travel, particularly if you are relying on a tight connection.

Where to find it. Follow signs for the terminal transfer or inter-terminal shuttle. Signage is clear in both buildings.

How long to allow. The transit itself takes only a few minutes, but that is not the number you should plan around. Allow at least 20 to 30 minutes door to door, covering the walk to the transit, waiting for the next service, the journey, and the walk into the other terminal. At peak times, or with a bus replacement in operation, allow more.

Accessibility. The transit is step-free and accessible. If you have booked special assistance, staff will help you between terminals — this is part of the assistance service and you should mention it when arranging help.

With children. Manageable, but factor in the walking at either end. Pushchairs are fine on the transit.

With heavy luggage. Trolleys are available in the terminals, though check whether they can be taken onto the transit itself. Practically, this is a case for travelling light on the transfer or for allowing more time.

If you are unsure which terminal you need, ask before you travel between them. Airport staff at either terminal can check your flight and tell you where you should be. It is much better than guessing and crossing twice.

A note on connections. If you have a connecting flight involving a terminal change, allow considerably more time than the transit journey suggests, and read the connections section later in this guide.

Arriving at Gatwick Airport

Here is what happens, in order, from the moment the aircraft doors open. This section is written especially for first-time international visitors to the UK.

Leaving the aircraft and following signs

Disembark and follow signs for Arrivals and UK Border. Do not follow signs for Flight Connections unless you are connecting. Depending on your gate you may have a substantial walk.

Passport control

At the UK Border you will pass through immigration control by one of two routes.

eGates are automated passport gates available to holders of eligible passports. Both the list of eligible nationalities and the rules for children travelling with adults have changed several times in recent years, so check the current position on GOV.UK before you travel rather than relying on what applied last time.

Staffed desks handle passengers who are not eligible for eGates, or cases where the gates cannot read a passport. Queue times vary considerably depending on the time of day and how many flights have landed together.

UK entry requirements

Requirements depend on your nationality and the purpose of your visit. Some travellers need a visa. Others need an Electronic Travel Authorisation (ETA) obtained before travel, under a scheme that has been rolled out progressively across different nationalities.

Check GOV.UK for your own nationality well before you travel. These requirements are enforced at the point of departure, not on arrival — if you have not obtained what you need, you will not be allowed to board. Do not rely on a friend's experience, or on a travel blog, including this one.

Baggage reclaim

Follow signs to baggage reclaim and find your flight number on the screens to identify your belt. Trolleys are available.

Customs

There are separate channels for passengers with nothing to declare and passengers with goods to declare. Allowances cover alcohol, tobacco, cash above a threshold, and goods over a certain value, and the penalties for getting it wrong are real. Current allowances are published on GOV.UK.

Lost or delayed baggage

If your bag does not appear, report it before you leave the baggage reclaim area. This is genuinely important — resolving it afterwards is far harder. Find the baggage services desk in the reclaim hall, report the missing bag, and keep the reference number you are given.

Responsibility for delayed baggage sits with your airline, not the airport. The airline arranges tracing, delivery and any compensation. Keep receipts if you have to buy essentials, and notify your travel insurer.

Meeting someone at arrivals

Each terminal has a designated arrivals meeting point. Agree the terminal and a specific point in advance — "I'll meet you at Gatwick" is not a plan when there are two separate buildings.

The person meeting you cannot see when you clear immigration, and clearing the border and baggage can take well over an hour at busy times. Anyone waiting should check the flight's landing time and add a realistic buffer, rather than arriving at the scheduled arrival time and standing in the hall.

Finding the railway station

From the South Terminal, the station is directly connected and clearly signposted from arrivals.

From the North Terminal, take the inter-terminal transit to the South Terminal, then follow signs to the station. Allow extra time.

Finding taxis and private hire

Official taxi ranks are located outside both terminals and clearly signposted from arrivals. Fares are metered.

If you have pre-booked a private hire vehicle or transfer, follow your operator's instructions — your driver will typically meet you inside the terminal at the arrivals meeting point, or direct you to a designated pick-up area.

Do not accept transport from anyone who approaches you inside the terminal. Licensed private hire vehicles in the UK must be pre-booked, and legitimate drivers do not tout for business in arrivals halls. Use the official rank, or a booking you made in advance.

If you need assistance

If you have pre-booked special assistance, staff will meet you at the aircraft. If you need help unexpectedly, contact any member of airport staff, or use one of the assistance call points located throughout the terminals.
