This is my first mileage run ever. I'm trying to requalify for Gold in 2003.

Here's the routing that I have found.

BWI-DTW-SDF-MEM-LAX-MEM-SDF-DTW-BWI

Fare is $261.50 for a total of 6,232 miles.

Can anyone help me find a cheaper fare or a better routing with more miles?

Should I book this immediately?

Thanks for you help.
