Tiger Airways Singapore, flight TR717 from Perth to Singapore, was postponed on Saturday night after the captain became concerned about his crew working overtime.
Because of its low-cost, the airline has no stand-by crew at destinations other than Melbourne and Singapore.
Matt Hobbs, spokesman for the airline’s sister company Tiger Airways Australia, said he didn’t expect overtime issues would be a problem for Adelaide passengers to Melbourne.
“‘They (international crew) can work for 10 hours straight so I don’t think they will go out of hours in Adelaide because it’s a 50-minute flight.â€’
Angry passengers were informed of the flight cancellation at 10.30pm, three hours after its scheduled departure, and were told to go home and return the following day or stay at the airport.
