There are a range of short haul destinations that NCL still lacks, to ensure a good coverage of european routes, whether they be operated by loco, charter or full scheduled carriers. Maybe the airport management may well come back with a few new announcements from the Routes conference, lets hope so.
Madrid, Venice, Croatia, Scandinavia, Germany, eastern Europe, Athens, more charter variety instead of a milliion flights to ALC, PMI, IBZ and AGP? The european business centres of FRA etc surely could sustain a regional service, though slots are obviously a problem?
Maybe existing services could be increased, the LH DUS seems to do very well, as is the CPH?
