Interestingly enough, people didn't provide much sympathy towards her and even accused her of propping her feet up in between the seat and the window, which isn't the courteous thing to do on a flight.
One person on Instagram wrote: "When you put your feet on an ARMrest that isn't your designated ARMrest …"
"Only yourself to blame. If your feet are somewhere they can be "drawn on," then they are in the wrong place," another added.
A third wrote: "Makes for a funny story. How can you be mad? It's cute. But also keep your feet off someone else's chair, and it won't be an issue."
Additionally, the travel account @lifesatripwithsk had a summary of the incident and the fact that the traveler was wearing socks.
They said it's fine to wear socks on a flight as they are "clean," don't have an odour, and "stay in your own space and not propped on various parts of the aircraft."
