Contracts are now exactly the same for scheduled and charter, next summer most bases will have a mix of schedule and charter flights and it will be difficult to distinguish the difference between them.
Aircraft types depends on bases, at the moment CVT & DSA are only on the 737 fleet. Where as EMA are 757/767 checked.
CVT & DSA are rostered in a different way to any of the traditional Britannia bases as they are rostered to CAP371, where as EMA is rostered to several union agreements, such as only 4 flights between paired days off. Also at DSA & CVT crew clean the aircraft on scheduled flights, where as Britannia bases cleaners are contracted.
Any more questions just ask.
