Keep in mind the timing of runway construction aligns with launch of regional airlines restrictions on pilot flight times. Many smaller carriers have pulled out of airport/service due to this limitation and inadequate number of pilots.

Quoted from AlJaz article on Jan 4th - "Regional pilots, who often have a more demanding schedule and tend to fly shorter segments at odd hours of day and night, have a "sliding-scale" of maximum hours and can be set as low as nine hours a day, a considerable drop from the previous max of 14."
