weasil thank you for your reply to my post. I would not like to say that I am in anyway involved with a low-cost airline as when someone expresses such an idea on PPRUNe it is usually badly ridiculed, however I am researching a number of cities and pros and cons into the US airline industry, I think thats the best way to put it

!
The airline industry in the USA, especially on the West Coast simply fascinates me, and I have found that JetBlue has done a geat job of creating a high frequency, good quality service out of a major East Coast hub, and I am interested to see whether SFO is in a similar situation to JFK.
I would be very interested to see the answers to my before asked questions, whether anyone has any contact addresses for SFO and if anyone believes a new start up from SFI could flourish.
