I'm busily trying to figure out how to maximize my business travel for the next two years. I'll need to fly from Northern CA to Washington, DC about 10 or more times annually, and I'm able to fly business/first. My goal is to use this opportunity to load up on both miles and elite status to assist with a hoped for RTW this summer/fall. OAK is my closest airport, and not needing to head to SFO each time would be a big plus, so US Airways is a potential choice. I know I have 5 RT between January 1 and March 31, so my plan would be: -- do an elite challenge for Chairman's -- Fly 5 RT routing OAK-PHX-DCA-PHX-OAK -- Fly 1st class According to MileCalc, each roundtrip would net me 26,253 miles. (This assumes that, during the challenge, I have Chairman's status and the bonus, but I believe that's accurate. If not, just let me know!) Is that the accurate number of miles? If so, I can easily meet the challenge, but I'm new to this and amazed that many miles pile up per RT, so I wanted to check to see if the numbers are right.
