First, let me move this thread to our "basic, simple question thread." Ocn Vw 1K, Moderator.

As a member, I'd say that your travel to qualify for UA confirmed regionals has to be on United/United Express metal only. My cite: http://www.united.com/page/article/0,6722,53017,00.html :

"Any elite member who earns 75,000 EQM or 90 EQS will get two Regional Upgrades. You can earn two more for every 25,000 EQM/30 EQS earned after that in the same calendar year - with no limit to how many can be earned. For 2011 1K members (earned as of January 1), these upgrades are in addition to the two you'll earn for each quarter in which you fly at least 10,000 paid, qualifying miles on United or United Express."
