Pros:Not much
Cons:Norwegian used an extremely old Wamos A320 aircraft instead of one of their own 787s. The seats were not only uncomfortable, but also so tightly arranged that my knees touched the back of the front seat, and I am an average 6 feet tall. Inflight entertainment options were available only through the Wamos app, which could not be downloaded on the plane (and Norwegian had not mentioned during check in). Unless for people with pre-ordered food, it was not possible to buy even water until about 3 1/2 hours into the flight. The flight to BCN on a Norwegian plane was okay, but the prospect of another such return experience makes it very questionable to book this airline again.
