Yeah, that would piss me off too. Ask. I have swapped seats with people before because they asked politely. Your lack of planning ahead and making sure you can buy seats together does not mean I should be expected to just accept that you want my seat. Act like a dick, get treated like one. Act like a civil polite person and you know what? I would probably have zero problem with swapping a seat with you.

The flyer, who later identified himself in a follow up TikTok video as Osaac Summer, had boarded an American Airlines flight on 6 July to discover his seat had been occupied by a child. A 20-second clip recorded by a fellow passenger, who goes by @lalawright2, captured the moment the young flyer gave the parents, who could not be clearly identified, a dressing down after reclaiming his seat.
