Their fiscal year ends on 31MAR. It's life or death for them to cling on to every last escudo to improve their balance (at least on paper) after the last two quarters which were not exactly shiny.

Claims for refunds should be shown as a liability in the balance sheet, otherwise the auditors (PriceWaterhouseCoopers) are not doing their job properly.

Even if Royal Maill did not find them with those letters yet as they claim it? ;)

Why on earth not? It is appalling the airline is allowed to operate a single flight while in its current legal position but since the CAA doesn't seem capable, direct action with bailiffs is absolutely the right way to go.

Does anybody know why today and I believe Saturday, Wizzair planes have been flying to Maastricht?

Usually at this time of the year there's a couple of inbound diversions from a fog-bound Eindhoven, but this is not the case for these. Today (27th March) alone there have been arrivals (and departures back to) Katowice, Cluj, Podgorica and Budapest. The diverts typically position back to Eindhoven and pick up their schedule. Not the case here (+ Eindhoven isn't fog bound today).

They seem to stay around 40 minutes, so they are not visiting the paintshop which is the usual source of inbound commercial airliners from companies not usually flying from here.

Looks as though they are flights rescheduled from Dortmund due to the German public service(?) unions industrial action today.

Titan 321NEO into LTN tomorrow for W9 doing a Palma then a Burgas. Something else sick? You wouldn't think Wizzair are short of aircraft?
Better than canx them on short notice, you can see the claims into the distance!

Currently Wizz Air Hungary operates as W6, and most (if not all) Wizz Air UK flights operate as W9. Wizz Air Malta has a W4 IATA code, AFAIK, use a W6 code, except for the occasional special charter or positioning flight. Yes, I know Wizz Abu Dhabi has 5W, but they are somewhat separate to the rest of the company.
I recall reading somewhere that Wizz Air Malta might start using W4 for normal scheduled flights in its own right, but can't remember where I read this... but I do remember wondering if this was really true or just a bit of unreliable gossip.

Would anyone in the know care to comment on this ?

It's happening. The GCOC of Wizz Malta (valid from yesterday) is published on their site and they started to notify passengers about the change of operator on existing bookings. 52 aircraft are already registered in Malta and all new deliveries are going to W4 as well.

So why the difference? Ryanair just use FR across the fleet for the EU registered aircraft?

G-POWT Still working for Wizzair out of Luton, this is day 8, is this a serious effort to keep the program stable or are they short of crew or late delivery of a NEO?

GTF issues?

She is due back at STN tonight. All W9 aircraft flying today as well.
Perhaps just an overlap in some Winter routes vs the new routes ie Istanbul.

Wizz Air perform worst for flight delays https://www.bbc.co.uk/news/uk-65228868

Given the network Wizz offers I'm surprised to see the level of delays mentioned along with fines and enforcement action.

The financial stuff seems to me unforgivable, but this... meh.

Reminds me of ships and flags of convenience from countries like Panama and Liberia.

Wasn’t it Wizz that encourage their pilots to carry on working when tired to help the airline out?

Or in this case, a bona fide EASA member state…

Wizzair U.K. is not an EASA but rather a U.K. AOC that the U.K. CAA is responsible for regulating. My personal view, having had significant involvement with Wizzair, is that it is a disgrace, both the airline and the regulation of it.

My understanding is that Wizz operates with aircraft on the AOCs of Hungary, Malta and the UK in some varying proportion. For example, daily flight W6 3504 at 21.30 from London Luton to Timisoara in Romania appears to have operated in the last week with aircraft either on Malta or Hungary AOCs on alternating days. Other flights from Luton are on UK-registered aircraft.
