Those numbers look pretty solid, decent loads both ways which bodes well. If 50-odd people from the UK end and 50-odd people from Cologne use the service, flights should be quite full once they've been running a few days and the two markets mix. Lyon looks better than I expected, if the Milan figures hold up they're into a winner.
Even if fares are on the low side, Stobart will of course retain ancillary spend from car parking and retailing. It will be interesting to see how the other routes perform and how loads hold up.
