Your choice of airline can be the difference between a five-star start to your getaway or the journey from hell, but from Spirit to Qatar, they all offer something different.
Whether you have a specific airline that you refuse to budge from, or simply go with the cheapest, there are plenty of horror stories no matter how much you've spent on a flight.
One travel fanatic has been branded 'brave' because he flew on an airline that's illegal in America and Europe.
Noel Philips is a plane-loving YouTuber who's also known for taking the world's longest flights in one trip.

Flying with Pakistan International Airlines, Philips took the trip from Kuala Lumpur in Malaysia to Islamabad in Pakistan.
Things got off to a rocky start, as Philips explained that those whose hand luggage was over the limit were sent to the back of the queue.
As he boarded his six-hour flight, Philips admitted he was simultaneously 'excited and nervous' about flying with PIA.
Still, with him upgrading to executive/business class, chances are his journey could've been a lot worse.
Aside from the plane being a bit battered and dirty, he said there was a 'fusty' smell but things were fine apart from that...well, apart from his wobbly seat.
PIA was originally banned from flying in America and Europe because after an accident, it was discovered that a lot of its pilots were flying without a license.
Although the ban was only temporary, it was then extended indefinitely.
Many in the comments branded him as 'brave', and not just because it was a dry flight without the option for alcoholic beverages.
Someone said: "Considering that their latest accident involved an aircraft crashing due to attempting to land without gear, you are one brave man."
Another added, "Omg Noel after all those crazy stories you've heard about fake pilots licenses within PIA... you're the man," and a third said, "You can kind of see why they are banned from Europe."
The flight cost $405, so it was definitely on the cheaper side. In the end Philips summed up that he thought it was 'sad' that PIA had half of its route 'decimated', but in the end, he concluded: "They're in a really tough place, They've got some quite old planes as well, and I really honestly do think, that given a little bit of investment in their aircraft, that PIA could be up there with some of the best airlines."
Will you be booking PIA for your next flight? Probably not if you're in the USA or Europe.
