Do Ryanair do any W sectors now.

Yeap LBA based aircraft dose LBA-IBZ-MPL-IBZ-LBA ever Thursday and Sunday afternoon this summer.

Rather unlikely next summer. British based aircraft won't be able to serve intra-EU flights while W-pattern LBA-IBZ-UK(any)-IBZ-LBA would be too long,

Having gone through FR's timetable for December for all TFS-UK flights, there will be 54 flights per week, split as 40 operated by aircraft based in the UK and 14 by aircraft based in TFS. They fly to 13 UK destinations from TFS;
5 Airports are operated solely by UK based aircraft (BOH/BRS/EDI/LBA/LTN)
6 Airports are operated by a mix of UK and TFS based aircraft (BHX/BFS/EMA/PIK/MAN/STN/)
2 Airports are operated solely by TFS based aircraft (CWL/NCL)

The Airports that have mixed based aircraft flying the route only have 1 or 2 flights per week from the TFS base. For example BHX has 4 flights per week, 3 by BHX aircraft and 1 by TFS. If there's no slack in the BHX based aircraft schedule, BHX could lose 1 flight per week, or another flight to make way for the TFS flight.
CWL (2 pw) and NCL (3 pw) stand to lose their flights, although various articles state that no routes will be lost. I can't see how they can operate W patterns on TFS without taxiing crews around and putting them up in hotels, which I can't imagine FR paying for!
Would a DUB-CWL-TFS-CWL-DUB be within crew hours?
Could a random routing using 2 aircraft work; Aircraft 1) DUB-CWL-TFS-DUB & Aircraft 2) DUB-TFS-CWL-DUB, also giving CWL a DUB flight a few times a week.

BHX-TFS
 

BHX has a spare operational aircraft on a Tuesday only (the 4th based often stays all winter operating at Christmas) and hopefully the Monday away based TFS flight will move to Tuesday. However BHX also served 3 times a week by a Faro based aircraft and once by an Arrecife based aircraft which can't be incorporated into the BHX schedule without the 4th aircraft operating.

I assume there is a 90 day consultation period for the base closures, which then actually allow for flights still to be sold in the short-term even if some are unlikely to operate such as CWL and NCL - TFS (unless of course they open new UK bases). Although I am not sure what the percentage rate is of over-turning a decision during the 90-day consultation period but I bet it is low.

Yes I did, thanks. LPL has 1 weekly flight that's operated by TFS based aircraft.

NEWCASTLE will have the same problem if/when the Gerona base closes

Depends surely on the registration of the aircraft. Any registered within the EU can operate into the UK subject to the appropriate agreements being in place. So for example an EI registered Ryanair aircraft could operate LBA - IBZ and then still be perfectly ok to operate IBZ MPL IBZ as Ireland is still within the EU.
It can then return IBZ LBA.
Only issue would be intra-UK routes (STN - EDI for instance) if the appropriate freedoms were not approved.
I think the only UK registered aircraft is G-RUKA and that potentially couldn't operate the IBZ MPL IBZ or any other intra EU routes if no agreements were in place post Brexit.

That's my understanding anyway but happy to be corrected if others know different!

Close but not quite. It's the nationality of the operator which is the main factor (in other words, what country has granted its AOC). So Ryanair UK will be able to operate UK domestic and (we assume) UK-EU. If it wants to lease in EI- registered aircraft to do so, that shouldn't be a problem (subject to agreement between UK CAA and EASA).

Commit - your understanding is exactly right. As EI- registered aircraft, Ryanair would have rights to continue flying as it does today. The only constraints would be on use of an EI- registered aircraft on UK>non EU services or use of the G-reg aircraft on intra-EU services assuming in both cases that no Brexit deal is reached.

The EU has already announced its "no-deal" position, which will essentially allow the current regime to continue for a limited period. It's one of a series of "mini-deals" that certain politicians deny exist.

I allow myself it's MRS and not MPL :)

Fair enough, but that is a very short term agreement, in the medium to longer term the situation is essentially as described by others. Corporate decisions will have to be made, and that will depend, to a great extent on the damage, if any, that is done as a result of a disorderly UK exit from the EU.

When will spring 2020 be put on sale in full ? I can see a number of routes that are on sale only up to late October 2019 - amd wondering whether these are going to end later this year, or if they will resume at the start of April next year...

Also waiting for the summer schedule of 2020. From Stockholm Skavsta several routes are loaded (Stansted, Alicante, Malaga, Bergamo, Brussels etc.) but many are not (including Barcelona).

TFS-NCL & TFS-CWL have been taken off sale, with the last flights on 5th Jan & 6th Jan respectively.

As well as :

Beauvais
Belfast
Bergamo
Cologne
Copenhagen
Eindhoven
Knock
Liverpool
Milan-Malpensa
Porto
Santander
Santiago-Comp.
Treviso
Valencia
Vitoria
and Wroclaw (announced few months ago)

From LPA few routes have been taken off sales such as

Bologna
Charleroi
Eindhoven
Glasgow-Prestwick
Hamburg
Krakow
Leeds-LBA
Liverpool
Oslo-Torp
Santander
Stockholm-Skvasta
Treviso

I am not sure for 3 routes LBA LPL and PIK ! routes were mentionned as year around but disappeared after October 2019 ! so if someone knows ! I do apologize in adavance if it's a mistake !

I guess this is related to the TFS base closure so there's an associated rejig of schedules

I'm sure i read TFS base is closing
