This ‘Nonstop’ Air India Boeing 787 Flight Isn’t Always Nonstop — Here’s Why

Air India's daily flight between Delhi and Toronto, operated by a Boeing 787-9, is technically advertised as a nonstop service; however, it frequently makes a refueling stop at Vienna Airport. This operational flexibility stems from specific requirements related to the aircraft’s certification process. The Boeing 787-9 requires a mid-air refuelling stop for regulatory compliance purposes. Fleet availability also plays a significant role, with Air India strategically utilizing Vienna to optimize its network operations. Consequently, passengers on this route should anticipate a scheduled stop in Vienna as part of their journey.
