FR
Problem is many airports have been trained by MOL to leave his planes and customers high and dry
You provide ooh service and submit the extra invoice for staffing and equipment
And he REFUSES to pay even when the Capt and local manager said they would pay, or he gets the invoice and pays a small fraction of it, a small fraction determined by him. , so
FR are 100% at fault here
No handler or airport will work for free , MOL has trained airports etc to be like that , even cabin crew are not happy working for nothing
Every airport, airport handler in Europe knows FR , you won't get paid for OOH service even when promised.
