I think economic forces are party to blame for this. Business class has gotten so much cheaper and better these days that it's hard to justify paying for first. The amount of competition among airlines trying to outdo each other in the quality of business class has led to really high quality products and low fares.<p>As a result, airlines are struggling to sell first. First cabins are regularly half empty. I've had many flights where I'm the only passenger in the first cabin, or with every guest having a separate seat for lounging and sleeping given low load factors.<p>A decade ago, business class wasn't so good, with angle-flat or recliner seats. Even when the seats were lie-flat, they were seldom private and with direct aisle access. It wasn't a comfortable experience, so for those who could, going first made sense.<p>This has led many airlines to reduce first class, or ditch it entirely. Singapore's first class product went from 8 seats to 4. United killed its GlobalFirst product entirely. American hardly has any routes. Malaysian is ditching first. In the western hemisphere, the only airlines with a real first class product left are Swiss, Lufthansa, and Air France. British and American also offer first, though have a poor non-competitive product.<p>Asia and the middle east is the only place left where first class is alive and strong.
