Yesterday she tweeted: ‘Denied from the business lounge once again for being under 18 and without an adult.. @British_Airways sort your shit out.’

And just in case BA didn’t get the message, she added a separate string of tweets, saying: ‘I’m not saying I deserve special treatment. Just saying if 16-18 yr olds are grown up enough to travel 5,400 miles around the world, I’m sure we can handle sitting quietly in the damn lounge.”

The airline’s policy is not to allow under 18s into the premium area, and soon enough, BA took to Twitter to calmly relay this message back to the Game of Thrones actress.

Hi Maisie. We’re sorry if you were disappointed, lounge guests must be 18 or older. We look forward to welcoming you soon,” they said.

Something tells us that when Maisie hits 18, House of British Airways had better watch out…
