If memory serves, your flight was extremely late leaving Gatwick due to fog. 
We turn an easyJet A320 (as used for Paphos) around in 35 minutes.  That's 180 passenegers and 150-220 bags off and the same put back on.  
Last month we achieved 85.9% OTP so we get a £50 bonus (only payable if OTP is above 85%).
