Luggage handlers at London Luton Airport have been caught on film hurling suitcases from an easyJet plane like rubbish bags onto a waiting truck.
Passenger Jonas Ozolins recorded the reckless workers unloading the bags and cases from a flight on March 13.
In the footage, the two men stand on the back of the truck, which will eventually transport the cases across the runway to the airport terminal, the Daily Mail reports.
They are seen hurling the cases, carrying precious souvenirs and gifts, onto the back of the truck.
Some of them even crash, seemingly unnoticed, onto the runway below.
It is understood the baggage handlers work for a company called Menzies Aviation, who have contracts for this work at most UK airports.
Luton airport told the MailOnline the contract was awarded by easyJet.
Jonas uploaded the video with the caption: "Idiot."
He followed it up with the comment: "This sums up well some of the worst. Hope these idiots get kicked in the face.... and then fired."
It has been viewed thousands of times and attracted hundreds of comments from other outraged airline users.
One wrote: "Idiots is putting it mildly."
Another added: "Hope they take care of our bags better than that when we come to London."
A spokesman for Menzies Aviation said: "Menzies Aviation considers the safe conveyance of passengers' luggage to be a matter of the highest importance.
"The behaviour displayed in this video is unacceptable, and an investigation is already under way. We will take whatever action is necessary to ensure that such behaviour is stopped, and our professional standards are upheld properly in future."
An easyJet spokesman said: "We have been assured by our provider that this is being investigated. We work closely with all of our airport partners to ensure our passengers' bags are handled securely."
A spokesman from the airport said: "London Luton Airport (LLA) requires all partner agencies working at the airport to meet our high standards.
"We are working with the ground handling company responsible who have confirmed that an investigation is underway and that they will take any necessary action to prevent such behaviour happening again."
