Jet2.com Timetable
Normally it works OK 90% of the time or at least it did about 6 weeks a go. Perhaps they are loading flights and destinations and the facility is down for the moment. Certainly there would appear to be difficulties to access their entire web site at the moment or maybe it's my Internet connection!!
If it were possible to see the timetables it would be possible to get a fairly good idea if there are going to be ALC based aircraft by the schedules and departure times from ALC......
