The union representing flight attendants for Delta Connection carrier Compass Airlines said its members have voted to authorize a strike in the event negotiations fail to reach an agreement that can be approved.

Of flight attendants that voted, about 94 percent were in favor of authorizing a strike, according to the union on Friday.

The strike authorization vote does not signal a strike is planned, and the union said the flight attendants “will continue to provide the premier level of service we provide to Delta’s flying public.”

“We are sending a clear message to management that we will do whatever it takes to get a fair contract, one that includes a living wage,” said the Compass flight attendants union leader Catriona Bagley in a written statement. The flight attendants would have to clear a number of hurdles to be able to strike under the Railway Labor Act that governs airline labor relations.

Compass said it remains confident it will reach an agreement.

Compass, owned by Trans States Holdings, operates flights from Delta’s hubs in Minneapolis and Detroit.
