01:30 PM EDT, 07/16/2024 (MT Newswires) -- United Airlines (UAL) flight attendants will vote whether to authorize a strike as "frustrations in contract negotiations" continue, the Association of Flight Attendants-Communications Workers of America said Tuesday.

The union, which represents 28,000 United flight attendants, said the vote will open Aug. 1 and close Aug. 28 as Labor Day travel starts.

The union said the flight attendants sought federal mediation eight months ago and have been working for three years under an amendable contract.

United didn't immediately respond to a request for comment from MT Newswires.

United shares rose 4.7% in recent trading Tuesday.
