People are flocking to social media in support of a woman who refused to switch seats on a plane with a mum and her children.

Whether it's on a train or a plane, staking your claim on your seat can be awkward, but CEO and founder of CONQUERing, Tammy Nelson, had more guts than most of us would when she walked onto her flight to find a woman in her seat.

When the woman asked to switch seats, Nelson refused and has since opened up about why.

In the video - posted to TikTok account @myconquering - Nelson can be seen sitting in her seat next to the window, not having switched.

The caption reads: "What would you do?

"I got on the plane and a woman was sitting in my seat and when I mentioned it to her, she said, 'Oh, you want to sit here I thought we could switch because these are my kids.' (She points to the two seats next to mine).

"I said, 'As long as it's a window seat, I'm happy to switch.' She points to the row behind us and says, 'Mine is right there.' (It's a middle seat)."

People have rained into the comments on the post to stick up for Nelson's decision to not move seats.

One TikTok user said: "The amount of families who aren’t paying to select their seats together is mind blowing! You were 100 percent right to not give up your seat."

"For her to assume and sit in your seat before asking you is already a huge NO lol," another added.

And a third resolved: "People should book seats together if they want to sit together."

Nelson later told Newsweek she declined moving seats to a middle seat as opposed to a window seat because she suffers from 'motion sickness during takeoff and landing if [she] can't see out the window'.

She says: "I also don't get a lot of sleep. I often try to get a little sleep on planes which is easier with a window seat.

"On that particular day, I only had 90 minutes of sleep the night before. And I was headed into a high-pressure work week where I would be presenting to 500 people and really needed to be at my very best so getting a little sleep on that flight was extra-important."

Unfortunately for Nelson, the rest of the journey didn't go much smoother, the mum 'super annoyed' she wasn't willing to swap and spending 'at least 15 minutes' complaining about it to another passenger.

However, like the TikTok commenters, Nelson thankfully received support from the other passenger who stuck up for her, appreciating the mum's desire to sit next to her kids, but noting she should 'plan ahead' next time and talk 'with the airline in advance or talk to the gate agent'.

'Grateful' for the support, Nelson notes the fellow passenger also flagged the additional cost of selecting seats to the mum.

The CEO said: "Clearly the woman just expected that I would make a change to meet her needs, not considering what she had done (or not done) that put her in that situation.

"She just expected me to flex my plans to suit her needs. There seems to be a growing trend of this entitlement in society and I think people are just sick of it."
