Singer Dua Lipa is not impressed with how a flight attendant handled her sister’s peanut allergy on a recent United Airlines flight. The “IDGAF” singer apparently does give one “F,” and it was enough to inspire tweets directed at the company.

Lipa wrote that when the flight attendant was informed of her sister Rina’s severe peanut allergy, he told her, “We’re not a nut free airline so if she has an [EpiPen] she might have to use that.” He also added, “We can’t not serve other passengers in your section nuts.”

A fan of the 22-year-old singer said that the attendant could have made an announcement suggesting there was a person with a severe allergy on the flight, but Lipa wrote that they did not.

did they not even make an announcement to the cabin that a passenger has a severe allergy?? like I’m sure everyone would be happy to hold off having a snickers bar when someone’s health is at risk. airline allergy policy legislation needs to change!!!

United Airlines’ allergy policy states that flight attendants can request other customers “seated nearby to refrain from opening and eating any allergen-containing products,” but they do that only “in some cases.”

United Airlines responded to the singer on Twitter, saying that it “can’t guarantee an allergen-free environment” and that it wanted to touch base once the singer reached her destination to address her concerns.
