Just had a flyer from GB Airways (British Airways) stating that their January sale is now on with up to 25% off. They are not the cheapest carrier, although service is usually pretty good and the discount makes them a bit more competitive for some destinations.
Prices appear to be quoted inclusive of taxes - so hopefully no hidden extras like baggage costs - and they provide food and drinks (unlike some of the cheap carriers). Reasonable prices for European & long Haul on the website (e.g Edinburgh - Paphos £90/ow incl. all taxes).
Hope this may be of interest.
