I'm thinking that this is not the end to Jet2's expansion at NCL. With gaps in the programme, other new routes are a possibility. They could definately go further afield than the average 2.5 hour flights locos usually go for. ACE to increase their presence in Canaries and possibly give NCL a scheduled link to Cyprus, particularly with a based 757, as definately a struggle for 733!
I must say that J2 seem to have it right. They are not just focusing on routes on a daily basis but expanding the scope and including routes which probably would not work on a daily basis, but which do work on serving them a few times a week. By doing this, it is widening the number of potential routes from the UK's smaller airports.
In the space of a year, they have managed to compete with easy, now serving KRK, PMI, AGP, VLC, LEI, AMS, BGO, ORK, MJV, MAH, PSA, TFS and CMF though not all during same season, i.e some are winter and some are summer only - again maximising possibilities.
