Flight attendants with Sun Country Airlines ratified a wage increase agreement reached between the company and its union.

The pay raise comes midway through the flight attendants' contract and was negotiated by the International Brotherhood of Teamsters on behalf of the airline's in-flight crew.

Under the new deal, flight attendants will make between $5.05 and $10.05 more per hour over the next three years. A flight attendant with 17 years' experience, the middle of the airline's pay scale, will see their hourly wage rise from $39.91 to $44.26 by the end of the three years.

Sun Country's flight attendants easily approved the wage increase. The group has 425 members.

"I and my fellow flight attendants worked hard to achieve this agreement," Elaine Rishovd, a 21-year flight attendant with Sun Country, said in a statement. "The pay increase will help our members headed into the holiday season."

The new contract will begin retroactively on Nov. 1 and will expire at the end of 2019.

Sun Country and its pilots union signed a new five-year contract last fall, giving the pilots a raise of between 20 and 30 percent in the first year.
