cancelling hundreds more flights as it recovers from this weekend s scheduling mess that grounded more than 2,000 flights. flyers stranded waiting in line for hours to try and rebook. cnn aviation correspondent pete muntene joins us now from reagan national airport and tell us what passengers are saying. this is not like southwest can flip a switch and get back to normal right away. it s really akin to unplugging the operation and plugging it back in again because it says all of these problems really started to cascade on friday. it really pins the blame here on air traffic control and weather issues, but what s so interesting is that the federal aviation administration issued a rare statement saying that those were not real factors on saturday and sunday when southwest had the lion s share of its cancellations. 800 flights cancelled on saturday. 1,100 flights cancelled on sunday. about 30% of southwest schedule
