A flight to Singapore left nearly four hours earlier than scheduled on Wednesday, leaving 35 passengers behind.

Scoot, a low-cost subsidiary of Singapore Airlines, said the late flight change was due to ‘difficult weather conditions’.

Flight TR509 was originally due to depart Amritsar airport in India at 7.55pm, according to The Independent, but it took off at 3.45pm.

The airline said the 280 booked passengers were told of the schedule change by email or text, but some customers who had booked via travel agents didn’t get the message.

India’s air regulator DGCA confirmed the flight left early leaving passengers behind and said it is investigating the incident.

An airline spokesperson told The Independent: “Scoot sincerely apologises for the inconvenience caused.We are currently working to provide affected customers with the necessary assistance.”
