Jerboy
I can't help with the reason other than the Jersey is usually the CDG-EMA
aircraft which was showing 5 hours late when I looked at midday.
The BHX based fleet have a couple of long turnaround times built in and it
is usually fairly easy to pull the BHX-NOC aircraft to cover any Mid-morning delays elsewhere (it has happened at least once this summer).
It usually involves delaying the Knock by 30-60 minutes waiting for the
PMI-BHX to come in. The Palma flight normally does the mid afternoon
Amsterdam and they can normally get the flights fairly well back on
sched by late afternoon. However the Knock is mainly a 733 and the Palma a 735 and if loads
are 131+ on the Knock it does not work.
It did not work in this instance if you check the Knock to BHX flight, as
it is about 3 hours late
At least the East Mids - Jersey pax didn't have to wait until the
Paris returned. I don't think I would have been too pleased if I was
on the BHX-NOC though.
