A Vistara flight from Mumbai to Delhi with 153 on board ended up in a precarious situation on Monday when it was diverted to Lucknow and landed with very low fuel levels. Vistara Airlines has told NDTV that the flight could have managed only 10 more minutes in the air before running out of fuel. The aircraft had barely 300 kg of fuel left when it touched down at Lucknow airport. With the fuel situation onboard increasingly critical, the pilots declared a "Fuel Mayday", indicating the seriousness of their situation to the Air Traffic Control.
