Alaska Airlines pilots are voting whether or not to strike.

Several other carriers are already saying passengers will see fewer flights this summer.

Alaska Airlines started its strike vote Monday morning, contract negotiations between the union and the company haven't moved much in two years. Balloting will end on May 25.

Alaska already cut two percent of its flights through June because of a pilot shortage.

JetBlue has also reduced its summer schedule while Delta pilots picketed at several hubs in April.

The Airline Pilots Association says they're seeking higher pay and better schedules.

The Southwest Airlines Pilots Association wrote a letter to executives warning fatigue levels were now the top risk to flight safety. Southwest Airlines acknowledged a rise in fatigue complaints

Several passengers we talked to say they pick Alaska because they have direct flights to cities like Milwaukee and Raleigh, North Carolina. Booking another carrier means a layover and a longer travel day.
