(CNN)Singapore's reign continues.

For the fourth year in a row, Singapore Changi Airport has clinched the World's Best Airport title at the annual SkyTrax World Airport Awards, announced Wednesday in Cologne, Germany.
    The Skytrax awards are based on millions of votes collected in passenger surveys.
    Many of those passing through the island city-state are clearly pleased with the airport's innovations, such as two 24-hour movie theaters screening the latest blockbusters for free, a rooftop swimming pool and a butterfly garden.
    "To be named the World's Best Airport by SkyTrax for the fourth year running is a significant achievement for Changi Airport and a clear affirmation that we continue to hit the right notes in our pursuit of service excellence," airport CEO Lee Seow Hiang said in a statement issued by SkyTrax.
