UK ETA for Transit: Airside vs. Landside Rules for Qatari Travelers (2026 Guide)

London’s airports are the busiest transit hubs in the world. For Qatari travelers, they are also becoming a source of confusion.

You book a flight from Doha to New York with a stop in London. Do you need a visa? Do you need an Electronic Travel Authorisation (ETA)? Or can you just walk to your next gate?

Here is the reality: It depends entirely on where you step.

One wrong assumption about “transit” can lead to denied boarding in Doha or detention at Heathrow. The rules are strict, and the difference between “Airside” and “Landside” is the difference between a smooth journey and a disrupted trip.

This guide clarifies exactly when you need a UK ETA and how to secure one quickly through etauk.ae.

Airside vs. Landside Transit: What Is the Difference?

Before looking at exemptions, you must understand your transit type. The UK Home Office defines transit based on whether you cross the UK border.

Airside Transit

You arrive at a UK airport and go directly to your connecting flight’s departure gate. You remain in the international secure zone (lounge). You do not pass through UK Border Control or Immigration.

Landside Transit

You arrive, pass through UK Border Control, and officially enter the United Kingdom. This happens even if you only intend to grab a suitcase or switch terminals.

Comparison: Do I Need an ETA?

Feature	Airside Transit	Landside Transit
Border Control	Do NOT pass through	Must pass through
Luggage	Checked through to final destination	Collect and re-check manually
UK Entry	No (International Zone only)	Yes (Official UK Entry)
ETA Required?	No (At LHR/MAN only)*	Yes (Always)

*Note: This exemption is subject to change. Always verify before travel.

The “Airside Exemption”: Who Qualifies?

If you are a Qatari national, you generally do not need a UK ETA if you are transiting Airside.

However, there is a catch. This exemption only applies if:

1. You arrive and depart from the same airport.
2. That airport is Heathrow or Manchester.
3. You have a confirmed onward ticket departing within 24 hours.
4. You have the correct documents (visa/entry) for your final destination.

The Gatwick & Stansted Trap

Not all UK airports have international transit zones. If your connection is through Gatwick (LGW) or Stansted (STN), you must pass through border control to reach your connecting flight.

This makes it a Landside transit. Therefore, you must have a valid UK ETA, even if you are only there for two hours.

When “Airside” Becomes “Landside” (The Hidden Risks)

Many travelers plan for an Airside transit but are forced Landside by circumstances. Without an ETA, this becomes a major problem.

1. Self-Transfer Flights

If you booked two separate tickets (e.g., Qatar Airways to London, then British Airways to Canada), your bags will likely not be checked through. You must exit Airside, collect your bags from the carousel, and re-check them.

• Result: You are entering the UK. ETA Required.

2. Terminal Changes

While Heathrow has airside buses between terminals, some connections require you to exit the secure zone.

• Result: You cross the border. ETA Required.

3. Flight Cancellations & Overnight Delays

If your outbound flight is cancelled and the airline offers you a hotel for the night, that hotel is almost certainly Landside.

• Result: Without an ETA, immigration officers cannot legally let you leave the terminal to sleep at the hotel. You may be stuck sleeping on an airport bench.

Why Smart Travelers Get an ETA Anyway (The “Safety Net”)

The Airside exemption is useful, but it is fragile. Relying on it means you have zero flexibility.

For a small fee, obtaining a UK ETA acts as a safety net. It is valid for two years and allows multiple entries.

With a valid ETA, you can:

• Leave the airport during a long layover to have dinner in London.
• Switch airports (e.g., arrive Heathrow, depart Gatwick) without stress.
• Handle flight disruptions comfortably by exiting the airport for a hotel.
• Enter the UK for future business or tourism trips without reapplying.

Considering the low cost and high validity, the risk of traveling without one rarely makes sense.

Frequently Asked Questions (Transit Rules)

Do infants need a UK ETA for transit?

Yes, every traveler requires their own ETA, regardless of age.

If you are transiting Landside (passing border control), even babies and children must have an approved ETA linked to their passport. There are no age exemptions.

Can I visit London during a 6-hour layover?

Yes, if you have a valid UK ETA.

The ETA grants you full permission to enter the UK. You can leave the airport, sightsee, shop, or dine in London, and return in time for your connecting flight. Without an ETA, you must stay in the airport terminal.

What happens if I land at Heathrow and depart from Gatwick?

You must obtain a UK ETA.

Transferring between two airports (e.g., LHR to LGW) requires you to travel on UK soil (public roads/trains). This is strictly a Landside transit, and you will be refused entry without a valid authorization.

Is the airside transit ETA exemption permanent?

No, the exemption is a temporary concession.

The UK government’s long-term plan is to digitize all borders, eventually requiring an ETA for all transit passengers, including Airside. We recommend checking etauk.ae for the latest regulatory updates before every trip.
