ABSOLUTELY NOT!
Costco recently stopped assisting with NCL flights... too many complaints.
We are having a horrible experience in regard to our upcoming Antarctica cruise. We live in Southern California, Los Angeles and NCL has our first flight leaving from a different COUNTRY! Canada to be exact. We've called them half a dozen times for the past month or so and they keep telling us they are working to fix it.... LAX is the closest airport with a hundred others between L.A and Canada...
It's ridiculous!
I will never use NCL air accommodations again..
