RCCs aren’t great...but they are better than ANY terminal, even when crowded. I have started using the "desks" at the locations that have them and I have to say that being able to send some e-mails and have some "personal" space is worth the 40K miles per year. I tried to justify spending the 40K on 2 domestic UGs or 1 intl upgrade BUT in the end, considering how much time I spend waaaaiting at the airport, it is WELL worth the miles.
I would challenge anyone who is holding off to get a membership in 05 with miles and I would say the chances are good that you will stay a member.
Thanks to ANC-ORD, I realized this sooner rather than later.
