I've been keeping an eye on the flights from Gatwick to Alicante on 19th Dec 13 back 12 Jan 14 as they had an 11am flight LGW to ALC and a return ALC to LGW at about 4pm which was nice timings.

Checked this evening and the flights have moved consoderably, LGW to ALC on 19th is now at 06:50am and the return at 12:40pm. Still ok timings, but just curious on what might have caused the change.
