Well it looks they are at least about to significantly reduce a base, with that as an excuse. That might of course not be the reason at all, but in fairness they have been communicating about the reliability issue for several years.

Also I do kind of get it from their perspective if there's a sharp contrast between bases, at least if one particular base is significantly worse than all the others. Although as Minrest said, they need to start thinking more like a big airline... some bases might have legit factors which make them different from others (ex. routine weather induced disruptions, or nobody wants to live there).
