AC employees must have the best free travel benefits in the industry.
From what I have seen, they can claim any seat on any flight; get priority over all paying customers and have unlimited access to seats.
This benefit apparently extends to employees family, friends, neighbors and anyone who might know an Ac employee.
I am often amazed at how many J class seats are taken by employees. It is not uncommon to see the employees, in uniform and not out-numbering the paying passengers. It becomes even worse when they hold impromptu union meetings during the flight.
