Edinburgh Airport has suspended its customer helpline to "protect staff" from verbal abuse from passengers whose luggage is missing.
The airport said removing the phone line would allow teams to work through a backlog of queries.
Hundreds of missing bags belonging to passengers are currently being stored at a warehouse near the airport.
Staff shortages have left the airline sector struggling to cope with demand this summer.
Edinburgh Airport said responsibility for passenger baggage falls to airlines and their handling agents.
Swissport, Menzies and WFS handle baggage at the airport. There have been reports of problems with passengers reclaiming baggage with all three operators.
