A fully booked SpiceJet flight reportedly left more than 40 passengers on the tarmac and was getting ready to take off before the mistake was discovered.
The Boeing 737 was scheduled to travel from Kochi to Mumbai in India but a series of incidents led to the flight being delayed by 75 minutes.
Owing to miscommunication after the delay, the left-behind passengers were taken to the wrong plane.
Flight SG154 was scheduled for take off from Kochi at 6.55pm local time on May 14 but had been delayed due to congestion at Mumbai Airport.
When it was finally ready for take-off at 8.10pm local time, the passengers were ferried between the terminal and the plane by shuttle bus.
