I am getting tired of the Trans States USE mess. Once again, Saturday morning we ended up Stranding FIVE passengers because of Weight and Balance of these GARBAGE AIRCRAFT. The other option was to carry only Five Bags and leave alomost FIFTY behind. Seems that TSA's approved W & B with the FAA needs to be amended. UNLIKE most Express Carries, TSA has the Carry On bagage added into the Pax Weight. It is something like 220lbs. Problem here is that if you only have 10 or 15 carry on's you can not recoupe the weight of the other 35 bags you do not have. Also they do not allow child weights. If you have aircraft 801-809 you are screwed on full flights. WHEN IS TEMPE GOING TO CORRECT THIS!!! We pay for them to operate our flights and they are just doing a poor job. Time to hold the Non Owned Express carriers accountable for poor service. Again, all the pax sees is OUR NAME on the aircraft.
