If anyone has noticed for small aircraft there are only 13 connections for the aircraft than 1700NM and over. if your flying less than 1700NM there are only 7 locations.
I believe adding extra AI airports nearer San Diego (except the 2 in the feedback section BOI & SMF) would be very helpful.
my suggestions would be these
USA:
Phoenix (PHX)
Tucson (TUS)
San Antonio (SAT)
Mexico:
Monterrey (MTY)
Durango (DGO)
Chihuahau (CUU)
La Paz (LAP)
Potentially on the IAD side you could always add
Mexico/Bahamas:
Cancun (CUN)
Havana (HAV)
Kingston (YGK)
San Juan (SJU)
these are some of the suggestions for connections from San Diego and IAD and even long haul flights from Prague.
opinions are appreciated,
please note i had looked at the feedback section and there are at least another 6 airports for IAD but nothing in the South West for connections to San Diego
