Why are they using LPA as a tech stop, it's miles off the great circle route MAN-CPT!
MAN-LPA-CPT is 5,806nm, compared with 5,336nm MAN-CPT.
Wouldn't something like MAN-MIR-CPT work better at 5,381nm, saving 850nm (circa 2 hours flight time) per round-trip?
Isn't fuel in the Canary Islands pretty expensive too (hence UK charters tankering fuel out there)?
