One thing I am guilty of is trying to get an extra legroom seat for free.
I’m 6ft5 and feel like my choice is between being forced to pay for something which I cannot help or be placed in a seat which is so small I end up damaging body.
However, this is usually something which takes up a few seconds of me just asking and moving on if they can’t.
While I have no data and this is just logical assessment I’d bet a lot of reason for the increase in these incidents is the way in which airlines have drastically increased fares and lowered services since the pandemic.
Since the pandemic airfares have doubled across the board and, with that, things like a complimentary checkin bag on an 8 hour flight have been removed.
Atop of that other complimentary things such as alcoholic drinks and meals have also been removed from many airlines. All the while operators have been implementing algorithms which force you to pay to sit next to the person with whom you are travelling.
It’s not an excuse for people to start abusing staff as that is unacceptable no matter the reasoning. Just trying to add some perspective
