I must say after reading the description of Delta's new service jetBlue definately has not a whole lot to worry about... Flying 757s would involve them having to fill those planes pretty efficiently to be profitable and those are much larger than A320s... not to mention I don't care how you fix it up they're still going to be louder and more obnoxious than A320s. Not to mention flying out of LGA the most delayed airport isn't going to help satisfy many customers... oh yeah unless they hire fresh flight crews using the same not so friendly delta crews will result in a very substandard copy cat of jetBlue... no offense to any die-hard delta fans out there...
