I think HLX only ran Cologne and Munich for less than a year in 2005. And despite less marketing than a British lo-cost would use it did get two or three times the numbers going to Dusseldorf for each route. Easyjet also got high numbers to Berlin until it messed around with the schedule and cancelled lots of flights. People do want to travel from NCL to Germany, and did so in much greater numbers when there were good services in 2005. Whether they are willing to pay high enough fares to make much money is another question.
