WestAir Charter is rolling out a new “price pledge” guarantee on Friday for all of its charter quotes. The charter firm–a division of Western Aircraft that operates PC-12s in the western U.S., Canada and Mexico–said its “price pledge” states “it will never bill clients for more than they were originally quoted,” with exceptions only for itinerary changes and impromptu overnights. “This means there is no guesswork for our clients,” said director of flight operations Jeff Matlock.
