WATCH | Woman refuses to give up empty window seat to other passenger, lies down across row instead

A traveller posted a TikTok of herself stretched out across three seats on a 15-hour flight after refusing another passenger's request to give up the empty window seat. The video went viral, and reignited the plane seat etiquette debate.

"No one is in my row and someone asked to take my window seat and I politely declined because I don’t owe anyone anything and I deserve to be comfortable for my 15-hour flight as well," reads the video caption.

The video has been viewed more than six million times in five days, attracting one million likes and more than 2000 comments. 

The overwhelming majority were in support of the woman, but some labeled the move as selfish, the New York Post reported.

Someone pointed out in the comments that passengers could refuse to give up their allocated seat, but they didn’t have the right to empty seats next to them.

"You don’t owe them your seat especially if [you] paid for it, but the other two seats are free for the taking as long as the crew is OK with it," she wrote.
