Air New Zealand has been crowned best airline in the world for the fourth consecutive year in the global rankings.
Etihad's opulent suites secured the carrier the accolade for best first-class cabin but for economy cabins, Singapore Airlines scooped the top prize.
Other winners of the annual Airline Excellence and Top 10 awards include Virgin Australia, which took the title for best business cabin and Emirates was praised for offering the best in-flight experience.
The 2017 awards were generated by global product and safety website airlineratings.com, which ranked the top airlines overall, best cabins of each class and highlighted the best entertainment, catering and cabin crew worldwide.
To be named one of the top ten airlines in the world, carriers have to show leading innovations in passenger comfort and must have achieved a seven-star safety status.
