Early on, when I started to travel for business regularly, I discovered that I could go anywhere in the world for 1-2 weeks with just my carry-on (hotel laundry service is a good thing). A few of the obvious advantages are:

1. They can't lose or break what they don't have.
2. You avoid the entire check-in process (no need to go to the kiosk just print your BP at home)
3. You save 30-45 minutes on the other end waiting for them.
4. Delays, cancellations, whatever, you are whole and not missing anything, thus able to go to plan "B" quickly.
5. Etc, Etc,Etc.

I have always thought that checking baggage is a rookie mistake and I always advise friends to not do it. Am I wrong? While I believe that I am right on this I see an awful lot of "Elite" tags on the luggage that is checked. Just curious...it’s Sunday afternoon and I am obviously very bored. How many of you very FF's check luggage?
