Flying to the UK: most visitors who don't need a visa, EU citizens included, must have an Electronic Travel Authorisation (ETA) before they travel, and most can no longer enter with an EU national ID card. British and Irish citizens, and people with permission to live, work or study in the UK, don't need an ETA. Apply on GOV.UK. Fares are searched across every airport we group under London (LCY, LGW, LHR, LTN, SEN, STN): check the departure and arrival airport on the seller's site.
