Fournier boy, please do not tarnish us all with the same brush. There are many crew out there that do not have 'new' cars and so what if they do, its down to each personal circumstances!
As for crew down, if the company roster flights with 18 crew then they should ensure 18 crew are on that flight. Why should our pax and the other crew suffer on that flight?
Also as for commission, this is a standard for any sales related job, so really it is not a bonus. The company want us to sell, they have to give us an incentive. Its the same for travel agents. Virgin want them to sell their seats so they have to give them an incentive to do it.
