SkyWestUnited6(CSi) Shares of SkyWest Inc, which operates regional flights for bigger carriers, including Jamestown for United Express, fell about 8 percent on Monday.

Almost 61 percent of SkyWest’s capacity was operated for United in the first quarter. United said last week that it plans to make changes to its regional flying that include cutting the use of 50-seat jets and replacing some of it with jets that have 70 seats or more.

The air carrier expected a second-quarter loss, and forecast a loss of $12 million to $14 million, or 23 cents to 28 cents a share, for the second quarter.

Analysts had expected a profit of 14 cents a share, on average, according to Thomson Reuters I/B/E/S.

The parent of SkyWest Airlines and ExpressJet Airlines, which carry passengers on behalf of Delta Air Lines Inc, United Continental Holdings Inc and American Airlines Group Inc, said it expected lower revenues because of missed incentives, such as on-time performance under its contracts with major partners.

It also said the results would include changes in its tax provision because of the expected loss and write-downs of equipment.

SkyWest also said that U.S. Federal Aviation Administration rules requiring more rest for pilots and beefed-up qualifications for pilots to operate commercial jets were increasing its crew costs.

SkyWest shares were off 8.3 percent, or 97 cents, at $10.68 in morning trading.

Jamestown Regional Airport Manager, Matthew Leitner was looking into whether SkyWest’s situation would have any implications on Jamestown airline service.
