Boarding a flight does take some time, as you have to pass through multiple screening points, showing your baggage, identity proofs and more for security checks. In fact, while boarding the aircraft, a final screening of boarding passes is performed to ensure that you are not getting on a wrong flight.
However, recently a man with a ticket to Patna, ended up landing in Udaipur, almost 1,400 km away from his original destination.
The incident took place on an IndiGo flight. Identified as Afsar Hussain had to board flight 6E-214 from Delhi, but mistakenly boarded 6E-319, which was flying to Udaipur.
