But if you want to look at air carriers, as in scheduled operations, numbers might be quite a bit different. The US tends to have a lot more places with air service/flights, given we don't have the rail-network of Europe with all the big countries so close. Air carriers should be the only important number, rather than chopping it up 121 vs 135. 135 includes both on-demand and commuter air-carrier, which feeds larger airlines. Of course "regionals" used to all be 135, then there was the rule change, but there are still lots and lots of 135 air carriers doing scheduled service to places every day. These should count just as much.
