Why do people here pontificate about things they have absolutely no idea what they are talking about?
On the inside of the four page A4 GPM forms, there is a tear off sticky strip so that it can be closed and the comments enclosed remain private. Virtually all GPMs handed back are stuck together.
The reason why Heathrow based crews score higher is because there is not the turnover of staff as there is at LGW. Crews are more experienced and professional. Reducing crew compliments will prove the point that the service onboard will be dumbed down to Gatwick satisfaction levels.
With 2600 less crew flying, I suppose someone here will argue that standards will improve. Gg has actually said that the reason why the service is better at LHR, is because on similar routes they have more crew.
