Here is a copy of the flight path of SWA flight 1380 yesterday. Airplane tail #N772SW. Not a complete planefag here, but how normal is it for a plane to deviate so much from its determined flight path from LGA to DA? Especially without weather. It almost looks to me that they were prepared to be diverted to PHL and didn't =want to make it to obvious. Maybe I'm in totally off base here.
