I see KLM is launching Fortaleza as well, complementing the JOON schedule. KL on days 1,4,6; JOON on days 5,7.
Seems a fairly play-it-safe route launch in that sense. Probably supported by good subsidies on airport charges.
I doubt many millenials will be overly concerned to make sure they are flying on the JOON days.
