Air India's suspension of service is "due to a combination of operational factors, to ensure the reliability and integrity" of the airline.

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.

Air India will stop commercial flights between New Delhi and Washington, the company said on Monday, citing a "combination of operational factors". The airline, owned by India's Tata Group, cited a looming shortage of planes and Pakistan's decision to close airspace as the main reasons for the cancellation of flights to and from the US capital.
