You would expect to see "first wave" departures from SOU to GCI and JER from S14, as there will no longer be a/c based on the islands.
The schedule changes in the online timetable (which appear to WIP) also now show that the NQY "based" a/c will operate NQY-LGW-NQY-BHX-NQY-MAN-NQY-LGW-NQY daily in S14 as suspected.
