Why would you help a flight attendant with her bags since it states in their contract that they are not to lift the bags of the passengers? All you are doing is creating back and shoulder problems for yourself. I know it may be not be nice to help them, but they need the exercise so they can lift the door in an emergency. The only reason they pass their recurrent in ATL or MSP is because the doors there have been used so many times they can lift the doors with a fingar.
