Not sure how this is 'the world's best airline'. I fly economy, and just had my 10th Qatar flight. The cabin crew is so uninterested and rude that it makes RyanAir look good. The food is a gamble; on some flights it's great, on some it's an embarrassment.
E.g. on a 7h flight we got served one average meal, and instead of a warm snack, we were given KitKat and chips.
On another 7h flight, no snacks were provided, and the crew did not do a second drinks service - too busy chatting.
Having flown long distances with many different airlines, I do not recommend Qatar in the top 3. Premium price, inflated reputation, for poor service.
