Do Americans need a UK ETA in 2026?

TL;DR: Yes. Since January 8, 2025, US citizens must hold a UK Electronic Travel Authorisation (ETA) before boarding any flight to the UK - including transit. It costs GBP 16, is approved usually within hours (allow 3 working days), and is valid 2 years for unlimited visits up to 6 months each.

The rule

The UK rolled out the ETA in waves: Gulf states first, then non-European visa-exempt nationals - including Americans - from 8 January 2025, and European nationals from 2 April 2025. In 2026 the system is fully in force. No ETA (or visa), no boarding - airlines check at check-in.

Key numbers from UK government guidance (gov.uk):

• Fee: GBP 16 (raised from GBP 10 in April 2025).
• Validity: 2 years or until your passport expires, whichever is first.
• Stay limit: visits up to 6 months each, unlimited entries.
• Processing: most decisions arrive within minutes to hours; official advice is to allow 3 working days.
• Transit: required even for airside transit at Heathrow and Manchester - this is the one that catches layover passengers. Reddit's r/ukvisa is full of travelers surprised that a connection through London needs authorization; even EU citizens now need one.

ETA vs. ETIAS vs. ESTA

How to apply in 4 steps

1. Download the official UK ETA app or use gov.uk - avoid third-party sites charging markups.
2. Scan your passport, take a face photo, answer suitability questions. Takes about 10 minutes.
3. Pay GBP 16. Approval usually lands within hours; allow 3 working days before booking tight connections.
4. The ETA links electronically to your passport - nothing to print. New passport = new ETA.

FAQ

Do I need an ETA just to connect through Heathrow? Yes. The UK requires an ETA even for airside transit, unlike most Schengen airports.

How long does approval take? Usually minutes to a few hours. The UK Home Office says allow 3 working days.

Does the ETA guarantee entry? No. It authorizes travel; a Border Force officer makes the entry decision.

Can I work in the UK on an ETA? No. It covers tourism, family visits, business meetings, and short study - not employment.

My ETA was refused. Now what? You must apply for a standard visitor visa (GBP 127, weeks of processing) instead.

Do children need one? Yes - every traveler, including infants, needs their own ETA.
