This is the only one I disagree with. I'm relatively tall for a woman (5'10") and look healthy and strong. I get asked all the time to help with people's bags. I'm not there to work for you. I make darn sure to only travel with luggage that I can lift by myself without asking for help. If you can't life the bag into the overhead, check it.

Now, the only exception is if you are a row or two ahead of me and when we land you bag is near my row. I will happily hand your bag up to you so you don't have to either swim against the tide or wait until the plane is empty to get your bag and I appreciate when others do the same. But that's because I was able to lift it myself originally
