Delta Air Lines Inc has scrapped a number of its flights to Dubai as competition with three Gulf carriers is hurting its business.

Delta will fly nonstop to Dubai from its Atlanta hub between four and five times per week starting Oct. 1, down from daily service this summer.

“The reduction comes amid overcapacity on U.S. routes to the Middle East operated by government-owned and subsidized airlines,” Delta spokesman Trebor Banstetter said in a statement, noting that daily service would return in the spring of 2016.

Delta is the only airline that flies between Atlanta and Dubai. Its service reduction will leave the Washington-Dubai flights on rival United Continental Holdings Inc as the only remaining daily nonstop on a U.S. carrier this winter.

Emirates operates a freighter service to Atlanta and currently flies passengers to nine U.S. cities from Dubai, with plans to add more. Qatar Airways will launch Atlanta-Doha flights in July 2016.
