Am I missing something? This must surely just be for "fun".

Intra-EU Y is 30k, and if it is EB only, then bound to be s/h aircraft. Maybe I am cynical but this is nothing but a marketing stunt - I am sure service onboard will be more Plus-like but the prospect of this is fairly horrifying (to me). I assume it will also be to a destination that has significant available hotel capacity. But imagine some length to flights, maybe PMI as it'll be a bit of winter sun?

I assume someone (as I guess it'll many be flight geeks) will start checking destinations where SK has filed an additional flight.

And whilst initially I thought this was a liability exercise it would hardly make a dent on the books...
