I recognize the reasons why you might think cabin crew should stow your luggage. In the old days we probably would have (but then again, in those days most passengers were men, or at least accompanied by men, who held manners which compelled them to take initiative on that). And today there are certain airlines which famously will help passengers with their bags. But notice I said “famously”, because it is rare enough as a policy that industry people take notice when it occurs. And we are amazed.
“It’s part of your job,” you might say. Weeeellll, that is sortof kinda maybe true(ish), depending on how you read our job description, which says something like “…will assist with stowage”. Of course I suspect this has purposefully never been clarified. Our airlines would certainly love for us to help you put your bags up in the bin (as would the passengers), which leaves everyone looking at us to do so. Except that if we do, and consequently get hurt, guess what the company’s position is? If you guessed, “it’s not officially part of your job to lift the weight of passengers’ bags, so you did so as a personal choice; we’re not responsible for your injury”, then you would be correct.
So, as much as we might sometimes want to help, most of us will not for fear of injury. Because if we get hurt slinging your bags, suddenly no one else thinks it was an action they approve of. And none of us want to be sitting out of work, injured, with no income while we pay out-of-pocket for Physical Therapy or shoulder surgery. (Even if one does get airline support, Worker’s Comp pay is capped at 2/3rd salary or a monthly max, whichever is lower. And on a Flight Attendant pay, 1/3 missing is catastrophic for most.)
And when it gets down to it, you get to the more obvious point: if your bag is too heavy for you, what makes you think it’s not too heavy for me? If you bring so much junk, and simply don’t want to check it, why do I have to be the one to haul it around? This is an argument you should be familiar with, known in the flight crew community as “You pack it, you rack it” or “you bring it, you sling it”.
Personally, if you’re a little old lady, are a mother burdened with babies, or have some injury and ask nicely (not presumptuously), I will help – and when I say “help” I mean “help” – not “do it for you”. I inform the passenger I will give an assisting hand but I will not take all the weight. This is because passengers like to ask for help, then not actually help! So one hand goes underneath to steady, but if you drop it, it’s falling on the ground. That’s my middle ground and it’s worked so far.
And never, ever in the modern history of Western airlines have I heard it to work if you just dump your bag in the aisle and walk away. Yup, that happens.
