Interesting and ambitious:
"US regional carrier Mesa Airlines has announced its plans to start a new carrier across the Atlantic in Europe. The Phoenix-based airline plans to utilize Bombardier CRJ900 aircraft, of which it is already an extensive operator in the US, for this joint venture. Mesa hopes to get its new project off the ground by the end of the year."
