How often are flights from SFO to AMS?

Im in San Francisco at the moment and my business schedule is pretty busy. Tomorrow, during the day, I have to catch a flight because I have some very important obligations in Amsterdam .The problem is that I dont know how frequently the tour SFO-AMS operates and Id appreciate if you could tell me, no matter what airlines cover it and regardless of the price of the ticket.

The line SFO-AMS operates couple times a day and you can make your choice concerning airline, the time of departure, price ticket, class and number of stopovers. First to inform you that there is no direct flight and that you can choose between one or two stopovers but I dont think the number of stopovers drastically affects the length of the journey. There are several Lufthansa and American Airlines flights on this route and I dont have any particular suggestion about the choice of the airline, because I think both are good and reliable. You can pick some other if the schedules for these two do not suit you. The price range is from approximately $1300 to $1611.
