For you having lived in San Francisco... you sure haven't much knowledge as to Industry, and Italians in the area!
You are saying Alitalia will not return to San Francisco or Los Angeles?
Perhaps, you should be working for Alitalia... that way you can tell them where they should and should not fly to! You may want to work for the San Francisco Airport Commission, that way you can tell them who they should not be marketing to!
Miami for fashion? .... news flash - Miami for leisure!
San Francisco for leisure?.... news flash - San Francisco for commerce!
... Let me correct you - from October to March these flights cater to Business Traffic.. from April to September these flights cater to Leisure Traffic!
Los Angeles for Leisure.. yes... Los Angeles for Commerce.. yes
You seem to also know more than anyone else on this forum about San Francisco, Italians, Alitalia, and such!
So... Lets see into your crystal ball!
American Airlines... SJC
? (how much longer)
Lets see how you do!
