It appears that as of the winter schedule, Flybe will add a seventh weekday flight between Jersey and Gatwick. The Gatwick based Q400 will replace that currently rotated down from Manchester to allow for an early morning arrival (08:30) into Jersey and a late evening departure (19:30) to London. Manchester will revert to a lunchtime service. The addition of an earlier arrival, over an hour earlier than is currently available with Flybe and British Airways, I think is welcomed, especially for the business community.
Doncaster, Luton and Newcastle also continue during the winter.
