The union representing nearly 1,000 flight attendants ratified a labor agreement with Frontier Airlines aimed at cutting costs, partly through a suspension of a 401(k) match program through 2015.

The Association of Flight Attendants-CWA says the contract ratified Monday also provides job security and other protections to the flight attendants. It's the first contract for Frontier flight attendants who joined AFA last year.

Frontier Airlines is a subsidiary of Indianapolis-based Republic Airways Holdings Inc. and has a hub in Denver.

Frontier previously said the contract is expected to save it $16 million in labor costs over a four year-period. It includes adjustments to vacation and sick accruals and other pay-related changes. In exchange, flight attendants would receive equity in Frontier and could participate in the company's profit-sharing program.
