DALLAS (AP) — A Southwest Airlines flight has made an unplanned stop in Las Vegas after the co-pilot became ill.

Southwest spokeswoman Brandy King said the co-pilot was fine after being checked by medics.

Flight 1015 was flying Friday from San Jose, California to Dallas.

Flight-tracking services showed that the plane was over southern Utah when it turned back to land at McCarran International Airport in Las Vegas, where it stayed on the ground for about two hours.

King said the plane resumed the trip to Dallas with a replacement for the ill crew member, who may have become dehydrated. He was not identified.
