some not to rough math....if a $250 transcon fare shows up this year, jfk-sfo-jfk would be 2500 pts at 10 cents/pt....3 trips is $750, which is probably the least cost...if you happened to be in ny or ca to start...shorter trips are likely to be higher.....to compare, dfw-fll/mia-dfw would have to be ~$100 for 10 c/pt...
absent another lga trip occurring, i would look for a 3500+ mi each way at 1 pt/mi or something like dfw-fra-dfw w/1 way @ 1 pt/mi & other @ .5....
find the trip w/a decent price, call aa & ask what the 1 pt fare would be & book if it fits....i think the agent fee is $30, but may have gone up....
