Back in the good old day, I used to earn RDM at a rate of less than 1.5cpm on big 3.
7 Tix. Nyc iah SLC/pdx. Using sdc to change routing to increase accural for 120usd. Upgrade to FC, earn RPU and GPU.
One year did 16-17 trascon for 1k. Many paid by bump vouchers.
Thing are not cheap anymore. 2cp rdm on main with no chance of upgrade is considered fair these days.
