Mumbai: Tata-SIA joint venture Vistara and Japan Airlines on Friday announced a code-share pact from February 28, making it the fourth such tie-up for the youngest full-service domestic carrier. Vistara already has similar tie-ups with British Airways, Singapore Airlines and its subsidiary and SilkAir. Vistara and the Japanese flag carrier already have an interline/through check-in partnership and the two airlines had signed an initial agreement in September, 2017 to pursue commercial opportunities together, Vistara said on Friday. Code-sharing allows partner airlines to provide seamless connectivity to their passengers through each others’ network. PTI
