Vietnam Airlines JSC is exploring an order for about 20 Airbus or Embraer regional jets to expand domestic capacity, according to people familiar with the matter. The Hanoi-based national carrier has been meeting aircraft manufacturers and airlines using the A220 and Embraer’s rival E2 jets as part of its deliberations, said the people, who asked not to be identified because the discussions are confidential. The unprofitable airline is unlikely to place an order for some months, some of the people said. Vietnam Airlines, Airbus and Embraer declined to comment. Local media reports in June cited company executives saying the carrier’s future need for single-aisle jets would depend on the progress of upgrades to small airports in Vietnam. Last November, Vietnam Air signed a memorandum of understanding with Boeing Co. for 50 737 Max jets. The airline currently operates about 95 aircraft, according to FlightRadar24.<br/>
