Service levels probably wouldn't suffer. The A319's, in the main, operate flights with a more relaxed cabin service. i.e City destinations and shorter routes. Therefore, people aren't buying as much and hence the service is generally quicker anyway.
The A320's operate the longer routes and these are often very busy service wise and the 4th crew member is obviously very much needed for cabin service.
Easyjet management have been harping on for over a year now about crew costs and ironically the crew at EZY have been screaming at them to reduce 319 capacity in order for them to become 3 man operated.
i quote the above on the assumption that you have never flown for a living....then you would see in general the whole post is incorrect.
Service levels would suffer inevitably, and invariably they do, on any airline that removes a crew member....
maybe not in the eyes of the passenger, but on the health of the crew members who work so much harder to keep up that service.
the crew at EZY have been screaming at them to reduce 319 capacity in order for them to become 3 man operated
I just don't buy into this argument whatsoever.....
reduce the crew, to reduce the number of employees, and reduce the prospects of career progression.
i'm sure there are hundreds of EZY crew screaming to work a lot harder!!!
