You get their emails, right? You're in the Spirit Club? It's pretty lame, your miles expire in 3 months with no addige (I just invented a word?), and without their credit card your redemptions levels are stupid, but if you're going to book with them anyway you can join it and you'll get emails with promos and stuff.

Also of note: there's offers out there for many more miles for getting the credit card, I already had a cc, but I did the app for the 2500 on the plane anyway - it was 2500 whether you get the card or not, so it worked for me.
