I got it when I wasn't sure which airline I would become elite with. It's fairly useful for me, but I'm thinking of ditching it for RCC when it's up for renewal so I can make use of hub RCC's. I don't get much use out of it beyond DCA's RCC. It's nice to have at IAH when there's a long delay on my UA flight, I can go to a CO lounge. I had hoped to use it more at IAH, but the bus wait and ride is too long.
