Our girls will be 9 and 11 when we fly in October. Our flight leaves at 6:50am so I am fairly certain that it is not a connecting flight and it will be empty when we board. I have to work the day before (at 7am) so it will be no problem for me to get to work a few minutes early and check us all in at the 24-hour mark. Even if we end up in the low B's (doubtful), we should still have no problems getting 2 sets of 2 seats together somewhere in the plane. We're all pretty easygoing so we will sit wherever we can find two seats together.
We are flying on points ($20 total for 4 R/T tickets) and I am not interested in paying another $100 for the EBCI. I don't think that there is any tangible benefit in our situation. If I knew that we wouldn't be able to check in at T-24 and that we had a good chance of getting "C" boarding, then I would consider it. The way I figure it, there are enough seats on the plane that if *EVERYONE* in the A and B groups took ALL of the window and aisle seats, then, only the middle seats would be available for the "C" group. Obviously, that is not going to happen. We plan to sit either window/middle or middle/aisle so I'm fairly confident that even if we are in the "B" group, we won't have any problems.
We are flying out of a small airport (FNT) so I think that may be an advantage as well. When DH and I flew out of GRR last November, there were a LOT of folks that had no idea how the boarding worked. Many of them had checked in AT THE AIRPORT and still squeaked in into the B group. It's funny because I checked us in about 20 minutes into the 24-hour window and we got A22 and A24 (I lost internet between the two and someone squeaked in between us

). For our return, DH and I logged in to the app while we stood underneath Spaceship Earth. We checked in at exactly the 24 hour mark and we got B11 and B12. We sat window/middle in the 12th row on our flight down and we sat middle/aisle in row 2 on the way home. Obviously, our boarding location had no impact on our location in the plane. We just decided that we will sit in the first set of two open seats that we come across. We saw quite a few folks sitting in the middle seats and "spreading out" until the remainder of their group boarded. I didn't let it bother me...we got on the plane, we had seats and we made it to our destination....that's all that matters

In October, our girls have been told the same thing...board the plane and sit where you want, as long as mom or dad can sit next to you.
