I'm doing more domestic travel this year. Don't ask me why, but I'm tempted to join either RCC or US Club.

US is running a Club promotion for NON-status members of $100 off for your first year. This effectively makes the US Club for a base member the same price as UA RCC for a 2P (I am Premier Exec).

Most of my travel is on UA metal. Maybe 4 segments a year are on US.

Is there any advantage to have one card over the other? I'm not worried about Int'l RCC access because of my *G status. But I know you can't use your RCC card to enter a US Club unless you're travelling on a US flight.

US Club members can bring 1 guest into a RCC (RCC can bring 2 into a RCC). RCC members have the same 1 guest limitation enterring US Clubs. I rarely have companions that travel with me (and never more than 1 guest).

Also, I can use RCC upon domestic arrival if I have a RCC card (but not if I have a US card and am not connecting to another UA flight).

That's all I could think of. Can anyone else think of other benefits/limitations to RCC vs. US Club?
