OK,
I need 3575 points for PLAT challenge completion. I have the following travel booked and/or ready to book and need help with the miles (distance). Needless to say I'm giddy with the expectation that I'll make it...
Booked:
8/27 RT DEN-DFW-YYZ and back, either Q or N class (sadly). So that's .5 point/mile.
Ready to book:
8/15 DEN-JAX (via STL, RJ145's

) one way. Cost is nearly $500 so I don't know what fare class it'll be.
8/18 LGA-DEN (via DFW) one way. Cost is nearly $800 - again probably not deep discount fare.
9/14 DEN-SJU (via DFW, MIA, or JFK round trip). AA must be running a wicked sale; prices to SJU around $294. I've
never seen fares that cheap. I wonder if I wait as long as possible if the fare code will go up? Although, if I AM Plat by then, it's a moot point.
Any calculations on when/if I will make it, and by what trip will be greatly appreciated. Also, as a side note, if anyone has any insight on how to make the pending trips better, please advise. I.e. aircrafts, seats, etc.
Thanks SO much ^
