This makes quite a lot sense for AY as in flights to BCN&MAD there are more Asian&Spanish passengers than Finns, the plane in practice is BCN/MAD-based and the flights will still be OW flights (unlike those operated by Smartlynx). Besides MAD&BCN based crew will have higher productivity as they can work both to and from Helsinki during the same day. For passengers this is much more welcome news than other alternativities (bag charges, even worse inflight service etc).

Would be nice if they could something with the schedules at the same time...
