Purchase Is 20 737-8 and 10 737-10 Airplanes For Domestic, Regional Growth Air India finalized an incremental purchase of 20 737-8 jets this month and an order for 10 737-10 airplanes that was previously listed as “unidentified” on Boeing’s website. Both purchases exercised existing options as Air India expands its route network to meet rising demand for the single-aisle jets. Air India will operate the new 737-8s, leveraging their dispatch reliability, fuel efficiency and range flexibility on high-frequency, domestic and short-haul regional routes. The airline also plans to deploy the larger 737-10 to maintain operational commonality and carry more passengers at low cost per seat.
