Tiger Airways flight TT413 had to divert and make an emergency landing at Adelaide Airport, Australia, on March 15.

The plane, en-route from Melbourne to Perth, had to be diverted after a strange odor was noticed in the cabin.

The flight landed uneventfully and all 171 passengers were provided free overnight accommodation.

The airline said in a statement, “Tigerair Australia apologises for any inconvenience to affected passengers, however safety is always our first priority and always comes before schedule … The airline is currently awaiting the review of the engineers’ assessment and is prioritising travel arrangements to get affected passengers to their destination as soon as possible.”
