Quite agree tartin tom. As an example the Luton-Malaga route is down to 2 weekly from next week for January and most of February then goes up again in March.
As for Gibraltar the airport is used for many ex-pats just living across the border into Spain - me included - but the one drawback is the problematic weather especially in winter. It is captains only landing as well. Although more handy to use Gib most of the ex-pat brigade who I know prefer to use Malaga as it has very few problems with the weather i.e. full Cat 3 capability. A couple of days in Gib I would suggest is wholly adequate to see the ´sights´ unless you are a ship spotter in that case it is like Miami of old for aviation enthusiasts!
Happy New Year to everyone
