This shows how incredibly bored I am.

It says the 51K airplanes are are the ER's and the 53K airplanes are the LR's. I'm also looking at airfleets.net and apparently there are so many more variations than I thought existed so I give up. I do find it interesting that Comair's average fleet age is 8.5 years! Skywest (Just for comparison!) is 4.4 years. I need to stop surfing the internet now, it's becoming bad for my brain.
by the way what were originally talking about?
