Must be my fault - I go and use the 11:50 LGW-JER and 13:30 JER-LGW twice in the same week and they take them away.
Interestingly, on my return I was sent a questionaire about flight timings on this very route. I did NOT indicate alterations either of the middle-of-day flights was required.
Also, the 11:50/13:30 combination made for a very convenient TP run. Breakfast at Gatters beforehand; Starter on the way out and Main on the return .. assuming CE of course which no doubt you would be for a TP run.
