Delta Air Lines will provide daily nonstop service between Des Moines and LaGuardia Airport in New York starting June 10. Flights will leave Des Moines at 7 a.m. and arrive in New York at 10:45 a.m. The return trip will leave New York at 8:59 p.m., providing business travelers with the option of spending a full day in the city. Airport Executive Director Don Smithey said he's optimistic that this will lead to more Delta flights, both to LaGuardia and elsewhere. "Des Moines has been a good market for them," he said. "Our market is now proving that we can support the service that the airlines are putting in here." The airport's passenger activity was up by 13.3 percent in January compared with a year ago.
