One of the Plat benefits I appreciate is being able to put up to 70 lbs. in a suitcase without having to pay extra. It lets me make trips with only one suitcase. Yesterday I was on a CO flight from SAN-LAX-HNL. The SAN-LAX flight was coded with a CO # and I received CO miles, but it was actually an American flight. My suitcase weighed 66 lbs and AA required me to pay the $25 fee. I asked the ticket agent if they didn't allow the extra weight allowance since I was flying on a CO ticket and she looked at me like I had two heads. I know this isn't a CO problem, but I guess I just wanted to vent over having to pay an extra $25 for a forty minute flight. I wish that if CO is going to use other metal they would try to insure reciprocity.
