NCL is an excellent base, doing extremely well. There is no reason not to take NCL, it's not going to disappear. It's also not really that small a base....4 x 737's and 2 x 757's at present, and I believe at least 1 more aircraft for next summer.
Excellent quality of life up here in the north, nice easy days out, very few if any 4 sector days. Couldn't be better.
