With Flybe baseing an EMB195 in Jersey from the end of the month Jersey will not see the end of the BAE146.
A BAE146 from what I can make out will operate the second Jersey-Gatwick-Jersey flight which is one of two extra flights the company are putting on for this winter.
The BAE146 will be used at weekends to operate one of the schedules that routes via Guernsey, as the Guernsey BAE146 does a charter out of Gatwick at weekends in the winter for skiers.
