Passengers travelling from Verona, Italy to Cambridge International Airport were shocked to find no one operating the passport control desk at the UK airport.
The Home Office is thought to have launched an investigation into the issue which isn't surprising given the stringent security policies at airports these days.
The flight between Verona and Cambridge only operates once a week courtesy of Eastern Airways.
Passengers were made to wait for two hours while a border security staff member from Stansted Airport was transferred to solve the issue, the Mail Online reports.
Those left stranded in the airport took to Twitter to express their anger over the unusual situation.
Laurent Gatto said: "Stuck for nearly 2h at Cambridge airport because first there was no staff for immigration ctrl, and now they can't get the computer to work."
Later adding: "Immigration officer not friendly at all. Threatened us to call the police. Ridiculous."
A spokesman for Border Force said: "We are very sorry to anyone inconvenienced at Cambridge Airport.
"Border Force set high standards for its performance and we are conducting an investigation into what happened on Saturday."
While a spokesman for the airport said: "It is highly unusual for our passengers to encounter UK Border disruption during their travels."
Cambridge International Airport has recently undergone a £1 million redevelopment and has a number of charter flights to the Channel Islands as well as Italy and a daily scheduled service to Sweden with British Airways.
Border Force is responsible for monitoring those entering the country as their website states: "We secure the UK border by carrying out immigration and customs controls for people and goods entering the UK."
