1. i'm 75 and had a stroke. i have never had a passenger or a FA offer to put my bag up. carry a cpap.
2. my wife is 67, and about 5'4". i have never seen anyone offer to help her with her bag.
3. i have never seen one of these strong young handsome men stop while boarding to help someone who obviously needs help. help is usually offered by 50ish year old men.
4. all the pretty boys are in a hurry to get their seats and turn on their electronic gear. particularly if they have an aisle seat.
if the airline wanted to reduce turnaround time, they would instruct FA's to help pack the overheads.
