The low-cost airline Vietjet has gained a ton of publicity, partly because of its bikini-clad flight attendants. The airline has now 40% of Vietnam's domestic airline market. They've made so much money that now they have just bought $11 billion worth of jets.

They bought some Boeing jets. No word on how many exactly.

Though it's clear what they didn't buy.

More lingerie.

Vietjet's CEO is on her way to becoming Vietnam's first female billionaire pretty soon.
