We all love the idea of flying first class - but unless we win the lottery, most of us will want to book the cheapest plane seats we can.
And now there's an official difference between cheap seats and really cheap seats: the latter are so cheap that they've even been given a different name: 'Last Class'.
The new informal name best describes the service you get with these seats (ie, none).

Industry analysts have said: "Passengers in Last Class are made to feel like second-class citizens from the moment they book until they leave the airport."
You probably won't even be able to get your hands on a packet of peanuts.

While Last Class passengers may be given a seat with ordinary economy passengers, those in Last Class wouldn't be able to make changes to their tickets, get a refund or reserve tickets in advance.
A woman told USA Today her flight was cancelled and since she had a LC seat she wasn't helped.
She said: "First-class passengers were given assistance in rebooking... Coach passengers were given a slip of paper with an 800 number and told to fend for themselves."
She officially experienced what has been dubbed 'Last Class' and the reason it's happening is so that airlines can meet their bottom line and because they can get away with it.
So booking the cheapest flight may not always be the way to go especially after you factor in the fees for checked bags or for that extra legroom or a window seat.
