Wizz Air told passengers at the departure gate that only passengers with tickets in the first 27 rows could board the plane bound for Budapest.

Not enough seats were available because the discount airline sent a smaller aircraft than necessary, leaving about 50 people stranded.

The handling of the situation caused by an alleged technical failure by the airline is unacceptable, the PMO said, adding that legal proceedings will be launched.

Wizz Air said it had to replace its Airbus A321 with an Airbus A320 with fewer seats.
