After pricing flights from IAD-LAX all day to go to
Disneyland and finding a good United flight, I've been contemplating how best to maximize our points/dollars. A one way United flight to LAX is 12.5k United miles (we'll be flying Alaska back most likely). I couldn't figure out how I wanted to make this work and thought maybe I'd just burn a little bit of URs to book it.
Well... it's fate. I just came home to a letter from United addressed to DH saying that he has 20,xxx United miles that will expire 8/31!!


I don't even know where these points came from because I can't remember the last time DH flew United, but I'm so excited!
So now I'm thinking I will book DH's flight with 12.5k of those points. My question for all of you is how I should handle booking my flight out there. I'll have 8k points left. Do I buy 4k more points? Is that worth it when the cash price is only $144? Do I transfer some points from Marriott or UR? Do I pay with CIP or Marriott Biz (vaguely recall seeing something about earning more Marriott points when booking United flights recently)?
TIA! I'm so excited that this trip will now become a reality!
