We recently wrote about “Sky Couch” seating and provided a general overview of Premium Economy services. Here are some reviews of various airlines’ premium econ offerings. They’re not our own, so we can’t vouch 100 percent, but they may help make your decision whether to spend the extra bucks on your next flight.

Rather than hoping you’ll have a whole economy row to yourself, now you can actually reserve an entire row. Air New Zealand calls it “Economy Skycouch.” Lufthansa calls it a “Sleeper’s Row.” Several others refer to it as a “Sky Sofa.” While there may be variations in exactly what is provided, typically it costs less than a business class seat, and less than purchasing the three seats separately.
