The budget carrier has been cancelling flights since last Saturday after rain and hailstorm hit the Delhi-NCR region last week. On Thursday it did not operate as many as 70 flights, citing reasons like planned cancellations and partial closure of the Bengaluru airport due to the Air Show. It had cancelled 49 flights on Wednesday as well. It said in a statement on Wednesday "The cancellations on February 13 were caused by several factors like anticipated weather conditions on February 14 and NOTAMS at various airports. This resulted in extended duty times which then made it necessary to re-roster our crew and optimise our operations,". Further, the airline said it has decided to curtail its schedule for the remaining period of this month by "approximately 30 flights a day". The carrier had said "This is in order to stabilise its operation and adjust crew rosters due to the reasons mentioned above.
