Interesting article on the changes DL and UA have made to their frequent flyer programs, and what it might mean.

"With 1,275 aircraft and flights to 369 destinations, Delta Air Lines is considerably larger than Swiss International Air Lines, which operates 90 aircraft and flies to 84 destinations. But it is neither Delta’s size nor its route map that is challenging the Swiss flagship carrier on flights between America and Europe.

Luring premium flyers from Swiss and other international airlines could be one of the consequences of a big change in how the Atlanta-based Delta and Chicago-based United treat their loyalty club members, according to several industry executives."
