Excellent news that easyJet are launching Gatwick - Jersey flights. The route is strategically important for the Island and, despite a good service from British Airways, the route can support competition.
The frequency and timings are better than might have been expected, although I would think the 07.00 out of Jersey with BA will be difficult to get seats on at times. Having said that, the attraction of easyJet will lure leisure travellers. 3x daily is a slight capacity increase on Flybe too, I believe.
