I've noticed something of great interest on the Ryanair booking system which will help to see what routes will and will not operate this winter. To do this select a flight route, and date within the winter schedule time (for pure ease always select a return flight exactly a week after to one going out) and search for flights. Enter the captcha and then on the next page, the slected date is highlighted in yellow in the calendar bars with three alternative days either side.
If flights are shown obviously the route will operate.
If it says no flights are available for all days of the week you can't tell whether the route won't fly at all or just isn't for sale yet, right? Well infact you can. If the days selected for outbound and inbound flights (highlighted in yellow) are both centralised (with three alternative days either side) on the calendar bars for both outbound and invound flights, it means that they plant ot operate this route at least once at some point of this week but just isn't yet on sale. Sadly there is no way of telling which day(s) or times of the day it will operate or how many times each day or week. It just shows that Ryanair is aplanning to fly the route at least once at some time in that week.
If the outward flight highlights the first day shown in the callendar bar (with the alternative days being the six ahead rather than three each side) but the inbound one is on the centrallised date that you selected (and shows 3 alternative days to either side like before), this means that no flights will operate at all and Ryanair are not planning to offer this route at this time.
I know this whole concept seems really bizzare and probably not intended by Ryanair and could be a glitch of some sort but it is generally accurate although is liable to change. Just use it as a guide as to whether a route you are planning to book will fly or not, never use this concept to book accommodation dates that you cannot later change just incase it does change, albeit unlikely to do so.
There seems to be a few people interested in services to the Canary Islands from the UK. According to this concept I've discovered, the following Canary Island routes will not operate in the winter season, all other UK to Canary Island routes should operate at least once a week this winter. Remember this could change but this is how it stands at the moment:
Bournemouth - All Canary Islands
Doncaster - Tenerife-South
London (Luton) - Fuerteventura
