It is actually their smallest base if I'm not mistaken, it was a few years ago. That probably helps with customer service although NCL does get quite a lot of customer service awards among others.
I'm confused by Jet2's though, that one strikes me as most surprising as it would seem that would lead to some slightly more substantial expansion, unless it means best performing in terms of highest LF's in which case it's in their best interests to take it slow and steady.
When do the 2014 year end caa stats come out?
