Screening out the codeshares on Flightstats (and remembering they are on GMT unlike mainland Spain) ... there is nothing between a Ryanair 73 from Valencia at 12.41 and the Tommy Cook 75 from Brum due in 10 mins at 13.47.
They seem to have lost a couple of German TUI 73 s in the meantime, due about a half hour ago.
When you say "Open Skies" you mean the all premium BA brand, so it may well be a charter. Maybe somebody with serious money and not enough space on his Gulf 650 is bringing his mates over to Golf del Sur for the weekend ?
