Got it, looks like you were doing an overnight in MHT whereas I was trying to do the redeye eastbound (cheaper).

I booked the following for $291.40:

Jan 19: SEA-SFO #1237
Jan 19: SFO-IAD #74 (redeye)
Jan 20: IAD-MHT #7233
Jan 20: MHT-IAD #7237
Jan 20: IAD-SFO #219
Jan 20: SFO-SEA #506

Using my $150 CS voucher, got this down to $141.40 for 7194 miles, or 1.97cpm.

When booking, the TA (Debra) could not stop giggling. She asked why I would ever do a mileage run so early in the year. I said that I made 1P this year and doubted I could do it again without a few of these throughout the year.

She giggled some more and left me with a parting, "I can tell it's going to be a lot of fun serving you next year!"

Made my night!
