GIOKOS: Speedy security lines, some restaurants, and lots and lots of seats, and that's what makes the best from an airport. Visitors to Singapore's Changi get much more. It's just been named as the world's best airport for the fourth year running. Travelers can spend their layover in a rooftop swimming pool, a butterfly garden or one of the airport's two movie theaters. Those luxuries become even more important when you're traveling around the world on budget airlines and that's what our Richard Quest is actually doing and he's recently passed through Singapore as you can see on this map. None of the other airports he has visited made the top ten list. And Richard filed this report from the home of the world's 23rd best airport, Sydney. Let's take a look.</s>RICHARD QUEST, CNN ANCHOR: Day six and we have made it half way around the world from where we began, we are of course, in Sydney, Australia. The flight from Singapore was my first experience of the long-haul, low cost airline in this case it was Scoot. We even had the CEO on board who pushed the trolley selling the duty frees. Whilst the flight attendants danced in the isle. Now, from Australia after I've taken the picture, and then had a local food, we start the long trek back to the northern hemisphere. Crossing the Pacific to Honolulu, on to Los Angeles, to New York, and then back to London. Remember what this is about, it's how the low-cost carriers have changed the way we fly. So it's ten airlines across nine countries in eight days, with one journey in low-cost. Richard Quest, CNN, Sydney, Australia.</s>GIOKOS: So of course, as Richard travels around the world, I'm standing in for him this week and we'll be back with more QUEST MEANS BUSINESS in just a moment.
