Traveling through the United Kingdom often involves a stopover at one of its major airports like Heathrow, Gatwick, or Manchester. If you’re not staying in the UK but just passing through, you might be wondering: Do I need a UK ETA for a connecting flight?

The answer depends on your nationality, your travel plans, and the type of transit you’re making. Let’s break it down step by step.

What Is the UK ETA?

The UK ETA (Electronic Travel Authorisation) is a digital entry permit introduced by the UK government. It’s required for travelers from visa-exempt countries who want to visit the UK for short stays — tourism, business, study (under 6 months), or even transit.

Unlike a visa, the UK ETA is fully online, linked electronically to your passport, and valid for two years or until your passport expires.

Do You Need a UK ETA for Transit?

In most cases, yes — you will need a UK ETA if you are transiting through the UK, even if you don’t plan to leave the airport.

The UK government requires all visa-exempt nationals to hold a valid ETA for:

• Airside transit (remaining in the airport between flights).

• Landside transit (passing through UK border control to change airports or terminals).

This rule ensures that border security checks are completed for all passengers entering or passing through the UK.

Exceptions to the Rule

You do not need a UK ETA if:

• You already hold a valid UK visa (visitor, student, work, etc.).

• You are a British or Irish citizen.

• You are a UK resident with indefinite leave to remain.

For everyone else, especially travelers from visa-exempt countries (such as the US, UAE, EU states, and others), an ETA is required for transit.

How to Apply for a UK ETA for Transit

The process is quick and simple:

1. Complete the online form with your personal and passport details.

2. Upload a passport-style photo in digital format.

3. Answer security questions required by UK border authorities.

4. Pay the application fee online via debit or credit card.

5. Receive approval by email, usually within 48–72 hours.

Once approved, your ETA is automatically linked to your passport, and airlines will verify it before boarding.

Why Apply in Advance?

Even though UK ETA approvals are usually fast, applying early ensures:

• No last-minute delays at the airport.

• Smooth boarding with your airline.

• Peace of mind that your travel documents are in order.

Experts recommend applying at least one week before your flight to avoid unexpected issues.

Final Thoughts

If your travel plans include a connecting flight through the UK, you will most likely need a UK ETA, even if you don’t plan to leave the airport. This requirement applies to all visa-exempt travelers and ensures smooth, secure transit.
