I recently paid about the same for a 4 hour flight from ORD-SEA. The ONLY reason I consider paying for an upgrade on domestic flights is for the bigger more comfortable seat. As a previous poster mentioned, if you're going to check bags, it will offset the cost of the upgrade by a little too.

I wouldn't even consider things like meals. They're not very good, and chances are you'll still have to bring on your own food for the kids anyway. Usually I buy something better in the airport even when there's a meal on my flight.

In terms of your original question, I would say if I saw a F ticket for SAN-IAH for $352 (your 233 + 119) I would jump all over it!
