I might never have achieved my childhood dream of becoming a world-class soccer player, but at June's Paris Air Show, I had the chance to see how some of them travel.Qatar Airways exhibited a Boeing 777-300ER dressed in a unique blue livery, decorated with the logos of the Champions League and Paris Saint-Germain.The airline sponsors the French soccer team, which is also owned by the Qatari sovereign wealth fund. This particular plane was used to transport them to the US for this year's FIFA Club World Cup. PSG play in Sunday's final against Chelsea. While the interior was the same as a typical Qatar Airways 777, it was certainly an added highlight knowing that some of the world's best athletes had been flying on the same jet just a few days earlier.Regardless, it's also safe to say that the interior is best-in-class. The day before my tour, Skytrax named Qatar Airways the world's best airline.From the cockpit to the award-winning QSuite business class, here's what it was like on board the jumbo jet.
