I agree with the other posters about A list status being yours only-but you don't say the ages of your kids. If they are ticketed and utilizing car seats on board, you can board in your own boarding position and at least take the seat on with you. You would be able to install the seat before the little one boards with mom at family boarding(if the kids are young enough) and at least ensure that you have 2 seats together.

If the kids are older, it may be tough to board later with them and expect to find 4 seats together.
