At the wages they pay, I would imagine there is a constant level of attrition, which would make me think they always need cabin crew at LGW. Back when LGW WW was still mainline, I remember EuroGatwick made significantly less than even Short Haul at LHR. I had a friend who lodged with me for a bit in London, and she was EuroGatwick and could hardly make ends meet.
On a different note, how do they roster you? Do you bid now?
