Looking at SMF and FAT, which both have very successful Mexico operations, Central America does not look nearly as likely. Only about 5% of FAT's Latinos are from Central America, about 8% in SMF.
It's a good point.
Speaking about the O&D market between California and Central America, no doubts that Los Angeles and San Francisco are leading that market, based on AV SAL-LAX 21x weekly, AV GUA-LAX 3x weekly, AV SAL-ONT 3x weekly and AV SAL-SFO 14x weekly.
We couldn't forget the contributions of their competitors serving the same market: United, Delta, jetBlue, Alaska, Volaris and Copa Airlines.
My conclusion is that the amount of passengers between these geographical areas has grown to higher levels, in less than 10 years.
AV would look carefully how SAL-ONT is working and based on their results, the opening of more Californian destinations will come true. Furthermore, AV has already announced the resumption of SJO-LAX as non-stop soon.
On the other hand, the demand of passengers from South America to California nowadays hasn't grown up lately. CM PTY-SFO has not resumed their operations, LA LIM-SFO isn't in service anymore and the old Brazil-Los Angeles flights are even suspended, until further notice.
