[Silent Bob]

I've had this happen on Continental when I sometimes try and sneak my 14 year old nephew into an exit row seat with me (He looks like he can be 17), you can seat them but then the computer will just say something at the end like "requires special" handling. However flying Continental often enough, when you switch to an exit row seat another screen pops up explaining all the rules, which specifically states must be 15 years or older. I believe it does so even on the website If their ages are in the system, the computer will simply make you start over. As for the baggage fee, did you get a receipt each time you were charged for the bag? If it didn't give you a receipt then you were not charged. When you pay for the bag on the website, you won't be charged until you get to the airport and actually confirm that yes you are checking a bag. In this case its helpful because if you decide to not check a bag at all you can then update the info, state you are not checking bags, and no charge to your card. Now if the machine did in fact charge your card each time, then each time you'd get a bag tag. If there was no bag tag, then no charge. If that's the case then the agents could have easily refunded any additional charges to your card.
