Nothing but praise for Continental from us, we will be doing our 4th flight with them this coming January, Birmingham to Newark then into Orlando Intl this year was the first time that we have used their seatback entertainment and we found it to be good, the games and movies entertained the kids pretty well.
Food - ok, nothing special just normal airline food, drinks are always available, if you want something else between services then the crew were happy to get it for you. If you have little ones the only thing to be aware of was I ordered kids meals for our DD3 and DS2, they gave them jarred baby food as they mixed up and gave us infant meals. There were no spare meals but luckily they didn't really want to eat that much.
Service - Agree that the crew are more mature, but in a way I like this as they are more experienced in what they are doing, we had a fantastic crew on the way back who saved a whole row at the back of the plane for us so that we could move and the kids could lie down to sleep on the flight.
We managed fine with the luggage allowance too, I think we may have been slightly over but they let us off!
One thing that we found handy was that they now have a US plug under the seat for charging laptops etc, we found this great as the kids were using my netbook for movies and we were worried about the battery running low, we needn't have as we could charge it - just make sure that you have your plug adapter in your hand luggage.
