Sure, they are comparatively cheaper than fully flexible fares. But my point was, are K, M, P and T not awfully expensive (too)?
At least as far as I recall, before the introduction of Finnair ticket types, K, M, P and T fares were the semi-flexible fare structures (typically earning 50%). You could not buy them from any websites, unless there was no remaining availability in the cheaper inflexible fares (typically earning 25%).
I would assume that is also the case for JV-constrained fares.
