One of the biggest challenges in 2009 for all the airline companies will be to preserve market shares, incomes, to find new sources for business and quite to reinvent themselves.  The Slovenian Adria Airlines teamed up with Mini adding promotional messages on their mini (around 50 seats) planes.  I liked very much the idea because I consider it extremely effective and targeted. And most of all, it can be done with a crisis budget having a very good impact.
