Air India will suspend services between New Delhi and Washington, D.C. from September due to aircraft shortages caused by upgrades to its Boeing planes and as Pakistan's airspace ban for Indian carriers affects its international routes.

Despite the suspension of direct flights to Washington, D.C., Air India said passengers will have access to one-stop connections to the city via other U.S. gateways, including Chicago, Newark, New York and San Francisco, thanks to partnerships with airlines such as Alaska Airlines, Delta Air Lines and United Airlines.

NEW DELHI- Air India has announced it will suspend its non-stop service to Washington, D.C., from Delhi, effective September 1. The decision means travelers from the U.S. capital will no longer have a direct flight option to India via Air India, which cited operational factors for the change.
