I am still confused. I am looking for the best TP earner in AA domestic F from SFO to DCA for the best value.

Firstly, as I read it, you get the same TPs as long as you're sitting in F regardless of the fare code? So "P" and "F" earn the same?

As BA.com's TP calculator won't recognise F on many routes what's the easiest way to calculate the number of TPs earned? As a multiplier of full economy? Or by mileage flown?

There are numerous ways between my cities but I'm trying to work out if a few hours extra routing, for example, SFO-MIA-DCA, is worth it over a more direct SFO-DFW or ORD-DCA. Or even, SFO-ORD-JFK-DCA.

If there's an easy table or something I've missed I apologise but I'd like to book fairly soon and I can't seem to find a simple, reliable way to calclulate TPs earned on AA domestic F.
