Zurich is on sale for June 2018 now, so it seems that at least one of the new routes from a new carrier has managed to stick.
Good news from both CWL and ZRH. There must be the possibility of a longer season and/or increased frequencies next year - IIRC LX increased the frequency to twice weekly for the entire season before the first flight.
I hope KEF can remain - the likelihood of D8 launching an NYC area flight seems to have reduced - at least until they have more real-world experience with the performance of the MAX. Hopefully the breathing space will give WOW a chance to establish.
