Are F,A, and P all first class seats? For instance a flight on seatcounter shows 3 F and 2 A fares left (all other fares are sold out). Does that mean there are a total of 5 first class seats, or only 3?

Sorry, I'm learning, but I did do a search and found a good link (http://members.shaw.ca/fewmiles/AA/recht/fares.html) and that leads me to believe A and P are also first class, however, based on some people's replies to other threads, it seems that F is all people talk about when using seatcounter (or expertflyer).

Thanks
