I'm not up on SNA
's limit has 25 slots for aircraft defined as "commuter" which the city defines as:
""Commuter" and "commuter carrier" means a scheduled carrier, certificated under FAR
Part 121 or 135, operating aircraft having a certificated maximum takeoff weight less than seventy-five thousand pounds and transporting passengers or cargo."
Currently I believe only Horizon and America West Express are operating with those slots, but Horizon's will become free when AS
The EMB-170 is listed with a MTOW of 82,673 lbs in the standard config and 85,517 lbs for the LR
. Unfortunately both models are larger than LGB
would allow under the commuter slots.
