PSA has never been year round for any Jet2 base.
MJV is a wierd one, the loads in winter are still good... not full but always over 100, so very suprised its dropped untill Feb. But the AGP will be going throughout the winter.
Maybe the Wed and Sun would be kept for the possible EWR/JFK but when we heard the rumours it was for a Thu/Fri to Sun/Mon not for Wed and Sun.
I cant see it happening or it would be on sale now... and because of all the probs with the 757 fleet I think certification for ETOPs have been pushed back.
