Could it be?

F- Ferry flight I think, sometimes used on BY flights

Yup:

P = Positioning

and E = Engineering I think ???

arn’t all of Excel’s flight numbers 4 digits long (e.g. XLA4034) – thus making the “P” that features in the empty flights’ numbers stand for “positioning”?

Well I have worked out that the one from Greece is the NCL baced one so this is how it would look, I think,

XLA10P from Gatwick 1215 – XLA4010 to Greece 13:20 – XLA401P from Greece 0820

XLA24P from Gatwick 0110 – XLA4024 to Funchal 14:40 – XLA25P from Funchal 2330

Looks like it, and all 3 running in empty too! Looks like they are all off out this evening with pax.
