I'm flying 727's and 737's.
Top man is flying 767's and 777's currently.
The guy below me is flying A300's, A330's, 757's and 767's.
So it's not a matter of small craft vs big craft. We're all flying large sized craft.
As a side note, they are both flying long range flights, and I am eating up the short range market, this could be why now that I've looked a bit more closely.
