I am not sure if the new agreement is still called Open Skies or if there is a new name for it. This is the agreement that would allow free travel between Europe and the U.S. between any city pairs.
What impact will this have on seasonal service? For example where I live at near IND we have the U.S. Grand Prix on July 2nd of this year. Unlike Christmas, Thanksgiving and spring break where people are going home to be with families or heading down to Florida this is very heavy international traffic.
While providing daily scheduled international service may not be practical it would be a very good idea to provide it over a 7 to 10 day period around the time of the F1 race. You would easily be able to fill the largest jets to and from AMS, LHR, CDG (each) around that race.
If airlines like CO, NW, AA, UA, etc were able to avoid the grief of government approval would they be inclined to offer nonstop service during a 7 to 10 day perior? We are talking about international arrivals of well over 10,000 during the race week. You may be even talking 25,000+. It is very significant.
