I tend to keep my points for more last minute travel plans when the sector fare costs have risen.
Incidentally, now that there is a new Flybe baggage tariff, on the JER-LGW flights BA are very competitive especially if you dial Flybe's 23kg baggage allowance into the equation so that it is "like for like". Plus, of course, you can choose your seat with BA for free when checking in on-line. I actually found BA flights to now be somewhat cheaper than a Flybe points "free fare" fight!
