Ski flights, Sofia et al (not)
The Sofia flight doesn't seem to be operating. CAA stats for December (latest available) show no CWL Bulgaria flights and I've not seen the flight appearing on the arrivals board.
CWL did have a weekly ski flight to Plovdiv in 2006 and in 2007 which I believe was shared with another airport, possibly BFS. In 2006 1879 passengers flew from/to CWL on it and the following year 2588. It did not operate last winter and is not operating this winter.
BRS also had a Plovdiv that operated last winter and in previous winters but it has been axed this winter. In rough terms it carried about twice the number of passengers than the CWL operation in both 2006 and 2007 but that may be explained by it not being a joint flight with another airport. BRS currently has two flights to Sofia on Sats, one TOM and one BGH.
On the broader front there does appear on the face of things to be a disproportion in flights serving the ski market from BRS and CWL.
BRS has 14 weekly ski charters (Chambery x3, Salzburg x2, Sofia x2, Grenoble, Geneva, Verona, Innsbruck, Turin, Toulouse and Kittila). Nine of these are TOM flights, using a combination of former FCA 757 and 320 aircraft, and Thomsonfly B 733.
In addition there are flights each day by easyJet to Geneva (including 5 on Sats and more than single daily on a number of other days), Innsbruck, Grenoble and Toulouse, and Ryanair flights to Grenoble and Turin.
There are over forty ski flights (charter and scheduled) each week from BRS whereas the CWL total is no more than about ten, if that.
