Thank you very much for that topjet, I feel much happier now as I was not looking forward to sitting in the airport for 8 hours! I am surprised they have a spare aircraft, as looking at their timetables on the FCA website they have 1 GLA-SFB 2x MAN LH and 2x LGW LH (not including Varadero) so there is something wrong there (bearing in mind they only have 4 LH aircraft)!
