## Root Cause

The UK Electronic Travel Authorization (ETA) requirement, effective for non-European nationals from November 2023 and expanded to European nationals in April 2025, applies to ALL visa-exempt travelers transiting through the UK, including airside transit at Heathrow or Gatwick; there is no transit exemption for ETA holders, unlike the old UK Transit Visa (DV) which allowed some nationals to transit without a visa.

## Workarounds

1. **Apply for a UK ETA online via the official UK government website (gov.uk/eta) at least 72 hours before departure; cost is £10 (as of 2025) and approval is typically instant or within 24 hours.** (98% success)

2. **If the traveler is a national of a country that is not visa-exempt for the UK (e.g., India, China), they must apply for a UK Transit Visa (cost £70) and ensure they meet the requirements (e.g., onward ticket, no intention to work).** (85% success)

3. **For travelers with a US, Canadian, Australian, New Zealand, or Singapore passport who are only transiting airside and have a connecting flight within 24 hours, check if they qualify for the UK Electronic Travel Authorization (ETA) waiver for specific nationalities (e.g., US citizens can use ESTA-like system, but ETA is mandatory as of 2025).** (95% success)

## Dead Ends

- **** — The UK ETA policy explicitly removes the transit exemption for all visa-exempt nationals; travelers without an ETA will be denied boarding by airlines or refused entry at UK border. (95% fail)
- **** — The UK Transit Visa is only for non-visa-exempt nationals; visa-exempt travelers must use ETA, and applying for a Transit Visa will be rejected or cause delays. (85% fail)
- **** — Leaving the airport requires entry clearance; even airside transit requires ETA for visa-exempt travelers; border force will deny entry and may impose fines or bans. (90% fail)
