How to get the best seat on a plane
Ever spent 15 hours stuck in the middle seat in economy class? Then this guide's for you.
How does one decide which airlines are the world's worst?
Poor safety or regulatory standards will be the most important factor for many people, and there are currently more than 100 airlines - most of which you probably haven't heard of - banned from EU airspace, or facing operational restrictions, as they don't come up to scratch. They include every airline from Afghanistan, Kyrgyzstan, Liberia, Mozambique, Sierra Leone and Sudan, as well as dozens from Indonesia.
The website AirlineRatings.com, meanwhile, awards carriers a star rating based on safety standards. Just 10 muster only a single star: Batik Air, Bluewing Airlines, Citilink, Kal-Star aviation, Lion Air, Sriwijaya Air, TransNusa, Trigana Air Service, Wings Air, Xpress Air.
Skytrax, another aviation ratings website, judges carriers according on the quality of their product and services.
Nine carriers (ANA, Asiana, Cathay Pacific, Etihad, EVA Air, Garuda Indonesia, Hainan Airlines, Qatar Airways and Singapore Airlines) can boast full marks. There are 40 with four stars, including Virgin, Lufthansa, BA, Air France and - surprisingly, perhaps - Emirates. A total of 107 airlines have three stars, including Ryanair, easyJet, United, WOW, Wizz, Norwegian, Thomas Cook, Monarch, Jet2 and American Airlines, the world's largest carrier.
But 21 airlines fall below that standard, according to Skytrax. Here they are (in alphabetical order):

The worst airline of all? According to Skytrax, it's Koryo Air, based in Pyongyang, North Korea. While all the others listed here received two stars, it was handed just one.
Previous passengers have described "perfunctory" emergency procedures, fizzy drinks that are "difficult to identify" and "uncomfortably loud" engine noise, while photographers on board its oldest aircraft have captured cockpits without digital screens and seats that fold forward. Furthermore, the in-flight entertainment usually consists of patriotic odes to the leader and indecipherable North Korean cartoons.
But not everyone agrees with the scathing verdicts. "It's a bit of a giggle, actually," Simon Cockerell of Koryo Tours, an independent Beijing-based travel company that specialised in trips to North Korea, told Associated Press earlier this year. "It's not Emirates. It's not quite the flying experience people are used to… [but] they are clearly not the world's worst airline."
Indeed, some of the passenger reviews on Skytrax's own website are in fact complimentary.
"Service was perfectly passable," wrote one UK user earlier this year.
"The burger was quite tasty and I got a beer with it," said another.
Even worse than Koryo might just be Baltia. Never heard of it? That's because it has never flown once in its 27-year history. Founded in 1989 with the aim of offering a "high-quality three-class passenger service", it is still awaiting its operational approval from the US Federal Aviation Administration. The airline is said to have failed the FAA evaluation seven times, apparently due to a problem with the deployment of its aircraft slides. Take that Koryo.
