Air China’s seats give you nice width, soft cushioning and slightly more complex seat controls. Not aboard this Air China 777-300, but on United Airlines very similar, but slimmer “Business First” versions.

Seat(s): We’ve been in these seats already. As you can see in the Seatguru maps below, United lines the seats up next to each other while Lufthansa angles them toward each other, cutting into the seat width even on the larger 747.I’m no Top Chef but I look like one in Air China biz-class PJ’s! – Showing off my new sleepwear at the modhop Travel Cave.

For example, United and Lufthansa both use a similar forward-facing business-class seat on much of their fleet (virtually all United planes that don't have the new Polaris seats). There's so much variation in how airlines install these seats and what planes they use them on, that it's hard to pick a configuration that always offers the most space.

Forward-facing seats, like those found on Lufthansa or United (the latter on planes that haven't been retrofit with Polaris yet).

Staggered seats, like those found on Iberia or Asiana.

Reverse-herringbone seats, like those found on Air Canada or China Airlines.

On airlines that choose to install more conventional business-class seats, you'll generally see one of the following three categories: Qatar and ANA have gone above and beyond with these cabins.

For United, that would mean Polaris aboard the Boeing 777-300ER. and their flagship business-class products. Let's start by taking a look at the big three legacy airlines in the U.S. Of course, little details can make or break an otherwise good seat, like how much spacing the airline decides to leave between rows, or whether an armrest retracts to give you more room. This means you'll find seats with identical 'bones' across many different airlines. More and more airlines are creating business-class products like Qatar's Qsuite or ANA's new 'The Room' business class, but most buy one of several common models of business-class seat and simply customize the color and finishes. But some business-class seats offer more length and width than others, so today we're going to look at which biz class offers tall passengers the room they crave. If you're tall, flying business class can really make a difference in how comfortable you are in the air.
