Oh, I was also going to mention that I got EBCI for our San Diego-Omaha flight for last Saturday. We got A14-17!!! I was shocked.
For our Omaha-Orange County flight I did 24 hour checkin and got low B's. However, I never heard them call for B boarding and we didn't get on till the end of the B's. We got 3 seats together in the very back and DH was a row away on the other side. We didn't have to change planes so while we were stopped, we moved up to the very front two rows. Worked out fine anyway, but I felt bad about being so knowledgeable about the process, checking in at 24 hours, and messing it up anyway. The moral is, pay attention and get up so you can watch instead of just trying to listen for it.
