A viral post on social media has sparked a heated debate over airplane etiquette and personal boundaries after a passenger admitted to refusing to give up an aisle seat when another traveler requested it.Posted in the "r/ AITAH" forum on Reddit, the note was titled, "Not giving up my aisle seat on a 15hr flight for an older lady with mobility issues."The user said he or she was "seated in the aisle seat of the bulkhead row in the middle section. Next to me was an older lady, probably in her 60s" — and the woman got up from the seat.'GATE
