A door lock malfunction left a flier trapped in the toilet of a SpiceJet aircraft for the entire flight yesterday. The passenger, flying from Mumbai to Bengaluru, had left his seat to use the washroom soon after the plane became airborne. Little did he know that for the remainder of the journey, the commode lid in the cramped toilet will be his seat. When the passenger tried to exit the toilet, he found that the lock was stuck. On figuring out the situation, the crew tried to unlock the door from outside, but failed. The passenger was rescued from his confinement only after the plane landed at Bengaluru and an engineer managed to unlock the door. SpiceJet has expressed regret and apologised for the inconvenience caused to the passenger. It has also said that the passenger will get a full refund on his airfare.
