all of my "mileage runs" have been on TW
, and F9
. Just depends on where you go, but I always do a 5-day trip and just be on a plane all day long until 10 or 11PM, then spend the night wherever I am! With TW
I racked up 324,500 miles one year (1998), On CO
every year I always rack up over 300,000 miles yearly now due to work, and on F9
I have just over 128,400 miles. I like doing the runs on CO
because of how easy it is to use the multi-city reservation part of their website, and I can add up to 6 city-pairs.
