Not quite, but I do try and fly UA metal to the extent possible. e.g. SFO-SEA, i have chosen to do SJC-PDX-SEA and back. On occasion i have even done SJC-DEN-SEA deliberately.

An india trip earlier this year was deliberately through BKK to maximize the EQMs on a pacific routing as well as United metal.

Those EQMs become addictive.
