I never thought I’d see the day, but United has finally finished outfitting its international fleet with flat beds in business class. This is a truly momentous milestone considering that the process started when I still worked at United and that was more than 8 years ago. But there are still some tricks to what you’ll get when you fly, so let’s go over all those quirks.

This doesn’t really need to be said, but while this announcement is just about Business Class, if you’re flying in First Class internationally, you will also have a flat bed. Anything that’s sold as First Class outside the US will be flat no matter what unless there is some kind of last second aircraft substitution.
