NEW YORK (AP) — Bette Nash, who was once named the world’s longest-serving flight attendant, has died. She was 88.

American Airlines, Nash’s employer, announced her passing on social media Saturday. The carrier noted Nash spent nearly 70 years warmly caring for customers in the air.

“Bette was a legend at American and throughout the industry, inspiring generations of flight attendants,” American wrote on Facebook. “Fly high, Bette. We’ll miss you.”

According to the Association of Professional Flight Attendants, which also shared a tribute to Nash online, Nash began her flight attendant career with Eastern Airlines back in 1957. The union noted she was based out of the Washington, D.C. area.

Nash’s position at Eastern eventually brought her to American, which bought out many of Eastern’s routes in 1990.

“Bette will always be an integral part of our history, and she will not be forgotten,” APFA stated.
