like the previous poster said, do a search and follow the instructions. You can get 500 eqm for about $55. Price could have changed due to the time of the year.
Points will post in about two days. Just to recap: link a co account with your ua account. Match status. Buy any fully refundable fare on CO, something with less than 500 miles. Use the elite maximizer to buy the extra 500 eqm. You have to fist click through the RDM offer to get to the elite maximizer. Once you have bought the eqm, refund the original flight.
