Gatwick doenst really bother me. Cologne is going to be a winner IMHO, right between AMS and FRA.
60" is actually too generous for a low cost business service (I think I will have to bring my measuring tape again to confirm.....) and same as Cathay long haul.

My biggest problem will be that I need the long haul trips on CX to secure my status every year. My short haul will remain with CX and there I use all the perks, so for the time being i stay where i am (untill they start flying me to Cologne J return for 13K)
