PIERRE, S.D. (AP) — Pierre and Watertown-area travelers have been experiencing scheduling difficulties after Great Lakes Airlines suspended flying operations.

The airline’s partner, Aerodynamics Inc., or ADI, will continue operating the Great Lakes Jet Express flights between Denver and the two South Dakota cities, but travelers said booking has become more complicated.

United, Delta and American airlines at the Denver airport told passengers this week that the companies won’t honor tickets from Pierre made through Great Lakes Airline’s booking system, the Capital Journal reported . Pierre passengers flying to a connecting flight in Denver will instead need to cancel that leg, get a refund and re-book the leg through ADI as a separate flight.

Passengers can use a travel agent, a service such as Travelocity or book directly with ADI, said Mike Isaacs, manager of the Pierre Regional Airport.

Great Lakes had been decreasing the number of cities it serves, but the company announced Monday it’s immediately discontinuing air routes. The airline operated in the West and Midwest for decades.

ADI confirmed after the announcement that they’d continue the air routes each week from Watertown to Pierre and on to Denver as scheduled.

Isaacs said ADI officials have been working to obtain an interline agreement with major airlines to resolve the inconvenience.

“Our apologies for any confusion in this matter,” ADI said in a statement. “We are working quickly to rectify this issue with all major airlines and expect to have this issue resolved quickly. We look forward to serving your future flying needs.”
