I was livid last year when I was made to pay excess baggage costs because my case was a fraction over the allowance. How could this be fair when the woman behind me – at least 17 st – paid nothing extra because she had a smaller suitcase? What good is travelling light if you’re tipping the scales in the wrong direction?

I don’t mean to be unkind. I hate it when people are bullied for their size. As a skinny person, I’m often subject to cruel remarks, and I understand that being fat can have a genetic component.

But this is pure economics. More weight on-board means aircraft need to take on more fuel. So airlines shouldn’t be criticised for charging by the pound.

Tall people already have to pay for extra legroom. Are they offended? Hardly.

As far as I am concerned, we need to stop being PC and let people take responsibility for themselves.
