Adfly
BA has until recently had a frequency of 5 daily services to Jersey. This summer they added another daily frequency to partially compensate for the loss of Flybe on the route. Flybe used to operate with 4 to 5 daily flights, often more at weekends during the summer. (Aircraft tended to be mainly 118 seater E95s with some dash 8 flights).
Those flights have been replaced by 2 to 3 daily services by Easyjet and the extra daily frequency by BA. Allowing for the larger size of BA and Easyjet aircraft actual capacity on offer is broadly the same as previously.
BA have no problem selling seats and always carry healthy Club Europe loads on the flights.
Room for both on the route with BA more than holding its own.
