Ok, I did the math, here's how the percentages work out by miles flown rather than departures for the LGA Expansion. We get paid by the hour anyway, so that's what matters. There are a few minor mistakes, as a few destinations have, for example, all CRJ700s but 1 CRJ900. I just counted that as all CRJ700s.

Also, it was easy to find the miles from LGA to each destination, and since I'm not going to get into how fast each plane files vs scheduled vs "we always fly faster than the flt plan" or whatever, the percentages still work out.

EMB145: 23.6%
CRJ700: 11.6%
CRJ900: 31.0%
E170/175: 20.5
M88: 9.3%
B737: 4.0%

Mainline is 13.3% while DCI is 86.7%.
