There may be only one major air carrier flying into Idaho Falls after Jan. 6, but Jackson Hole, Wyo., residents may be seeing more big jets.

American Airlines, which has flown into Idaho Falls since December 1987, will be curtailing service, Idaho Falls City Councilman Wes Deist said Thursday. Deist, chairman of the council's airport committee, said he learned of the decision Wednesday from airport Manager Jim Thorsen.American officials in Fort Worth, Texas, were unavailable for comment.

Delta Airlines is the only other major carrier serving Idaho Falls.

Carol Glenn, a ticket agent at the Jackson Municipal Airport, said she heard American would continue and probably increase service to the Wyoming resort city after pulling out of Idaho Falls.

Deist said he was told rising fuel costs have cut American's profits in Idaho Falls. However, he said, "I know they were making money here."

When the council was renegotiating the airport lease agreement with American earlier this fall, airline officials gave no indication they were considering pulling out, Deist said.

American started serving Idaho Falls in 1987 after negotiating an agreement with the Jackson Hole Ski Corp. to provide the resort with passenger service. Regular flights to Idaho Falls were added later, and the carrier currently makes two stops a day.
