The first idea is to avoid getting seats that are directly next to each other.
You see, if you are travelling with another person, she says you should instead book the window and aisle seat, because that means there's one seat in the middle between you and your travelling companion.
People who are travelling on their own are very unlikely to book into a solo seat in the middle of two people.
However, you do run the risk of that happening, and you being separated from whoever you're travelling with.
It does increase the likelihood of getting a bit of much-needed extra room on the flights, though.
That would definitely mean quite a bit if you were on a long haul flight.
Chances are that the person who books into the middle seat won't mind a swap, so there's that at least.
Chelsea illustrated what she means by putting the theory to the test on a flight from London to Corfu recently.
A video that she then uploaded to her Instagram showed that she'd managed to get it spot on, as her and her partner managed to get the full row to themselves.
It's a high risk strategy, for sure, but - as Chelsea says - 'you've got to be in it to win it'.
The next tip is a bit stranger than the first, and certainly takes quite a leap to get on board with.
The plan is to hope that the people who are getting on the plane with you are superstitious, and book yourself out a seat on row 13.
Those who think that the number is unlucky are unlikely to book themselves onto that row.
Strangely enough, some airlines already know about this and don't even have a row 13 on their planes.
Finally, she offers us this advice: "People tend to want to book closer to the front of the plane so choosing towards the back may increase your chances further - but it's all about how the specific airline allocates their seats (they're all different I'm afraid!)."
It's definitely worth combining them all though, as on her flight to Corfu, Chelsea booked on row 13, booking the window and aisle seats, and found themselves sitting completely alone and undisturbed.
