How many trips is that? If you got 4 to 5 Y,B,M,S fares for only $1300, those are extremely cheap prices for those fare classes.
2 trips from the midwest to the west coast. One was around 900, the other around 700. I just multiplied my MQDs by 8 for the mileage under the new program since I assume they'll be using MQDs and not full ticket price I'm at just over $1,400 MQDs. Multiple fare classes because the trip out is usually on a high fare class but the trip back is on a cheaper fare class.
