Twitter user Your Fat Friend has started a thread about what it’s like to fly “as a very fat person”, revealing the preparation she has to put in for every single flight she takes.

She explains: “I researched airlines for their ‘customer of size’ policies, many of which reserve the right to kick me off the plane, even after boarding.

“The rest require purchase of a second seat. If I don't buy one in advance, I'll be charged the day-of price. Today, that's $800 one way.

“I'm charged for that second seat regardless of whether one is available. I pay double for the privilege of staying on the plane.

“Even if I buy a second seat in advance, the airline may still sell it to another passenger. If they do, I won't be notified or refunded.”
