Jul 21 (TheWrap.com) - Maisie Williams, who plays Arya Stark of “Game of Thrones,” finally figured out how to stick ‘em with the pointy end — the pointy end of her social media account, at least.

The 17-year-old HBO star's character is famous for her fiery spirit, adaptive nature, and relative proficiency with a sword, but in real life she's making a name for herself as a disgruntled airline customer.

After being refused entrance to British Airways’ business class lounge for being under age (she won't turn 18 until April 2015) and unaccompanied by an adult, the up-and-coming starlet aired her grievances Sunday on Twitter.

Williams’ profanity-charged tweet, which now has more than 2,000 favorites, read:

Problem solved, right? Not so much. When you play the game of business class lounge disputes, you either win or you continue tweeting, apparently.

Williams continued:

Season 5 of “Game of Thrones” will air in next spring.
