I had to pay 30.00 extra for my 25lb bag! I paid extra for a certain seat and the plane was half full?

Airport wheelchair staff was in very short supply in Chicago. AA staff took care of us instead. Gate attendant in Portland was very kind and changed my seat so I could sit with my wife, without my asking for it.
