Travelers in the U.K. encountered technical difficulties when trying to access their electronic travel authorization (ETA), linked directly to their passport.

Travelers to the U.K. have been facing a system outage since February, hindering their ability to board due to technical difficulties. The digital authorization, a separate requirement from a visa, carries a fee of 20 British pounds, equivalent to approximately $27. Eligible travelers, including those from the US, Canada, and most European nations, can obtain an ETA for short-term stays lasting up to six months, valid for two years.

The approval process had been moving quickly prior to the system failure, with many applications being processed in mere minutes, yet applicants were still advised to budget at least three days for completion.

Travelers who delayed applying for authorization until departure day found themselves stuck due to technical issues in recent times. The Home Office remained tight-lipped about the onset of the system failure and its expected resolution time despite repeated queries. Meanwhile, some passengers on Wednesday afternoon were unexpectedly informed that their applications had been approved.
