Edinburgh Airport bosses have suspended the airport's phone helpline because staff are being overwhelmed by abuse from furious passengers.
Raging customers have peppered workers at the end of the Scottish airport's helpline with fury, leading many of them to quit.
The airport has struggled to find people to man the lines due to difficult nature of the job as travel chaos continues to impact travel hubs, the Daily Record reported.
Helpline staff were also inundated with missing baggage queries despite airlines being responsible for luggage.
The move came as MSPs warned passengers not to abuse staff after hearing 'multiple reports of passengers being rude and insulting to airport workers'.
One Edinburgh aviation source said some workers had been so traumatised they had been forced to quit their shifts.
The abuse has been linked to delays caused by staff shortages and passengers arriving too early for flights, lengthening queues.
The source said: "There has been a big rise in passenger anger but the abuse of staff is unacceptable."
Thousands of mislaid bags, including transfer baggage, have also built up in and around the airport due to staffing problems with handling agents.
Many customers have been unable to find their bags, leading to them to call the helpline in desperation.
A spokesperson for the airport said: "Our customer support team are currently seeing a large volume of queries, around 90 per cent of which are related to the baggage process which is under the control of airlines and handling agents, not the airport.
"Unfortunately we have seen a rise in the amount of abuse our teams are facing from passengers.
"Although we appreciate the frustration they are facing, it is not acceptable and there is no excuse for abuse.
"To allow our teams to work through a backlog of airport queries, and to protect them from this verbal abuse, we have taken the decision to temporarily suspend the phone lines.
"Passengers can still get in touch by email or using the chatbot function on our website."
The Scottish Parliament's Cross Party Group on Aviation also issued a warning about abuse and passengers turning up too early for flights.
Co-convenors Graham Simpson and Paul McLennan said: "Scotland's airports are facing challenges but passengers are not suffering the problems that are being experienced elsewhere.
"The airports and airlines have been very clear that there is no need to turn up early because that only adds to queues.
"We've also heard that passengers have been abusing staff and that is completely unacceptable and it just adds to the pressure they are under."
The airport said '90 per cent' of calls to its customer service helpline were about baggage despite this being the responsibility of airlines.
A joint statement from AGS Airports, owners of Edinburgh as well as Aberdeen and Glasgow airports, said: "Aviation is facing a global challenge as the industry experiences tremendous demand just a few months after the lifting of restrictions.
"While this has resulted in some issues, Scotland's airports are performing well in comparison to others.
"We know that some of our partners are facing difficulties in recruiting staff which has been a source of understandable frustration for some passengers.
"Unfortunately that is resulting in a rise in the number of incidents of abusive and disruptive behaviour towards staff.
"We cannot accept that as staff are working incredibly hard to get passengers to where they want to be and we thank the vast majority of passengers who have worked with us to ensure a smooth journey through our airports."
