Just flew NCL-BCN on Friday and BCN-NCL last night (Sunday) and managed to catch the F/O for a chat when he came out the cockpit (he promised I wasn't bothering him and he wasn't busy - I did ask to make sure) but he mentioned that NCL had a good year as an EZY base last year and things are looking good this year, 154 pax BCN-NCL and our outbound flight was very similar, I only spotted 1 empty seat outbound and I had a good scan whilst in the bog queue.
Anyway I mentioned to him that I'd love to see more from EZY at NCL, maybe a 4th based A/C and he said that with the fleet expansion and increased flexibility in the coming months and years, that NCL is likely in the running for expansion as it is doing well for them... We shall see!
I must say 154 pax (156 with 2 no shows - I checked the computer screen at BCN) is very impressive for this year!
