Twenty-eight airlines currently offer premium economy cabins on transoceanic routes. So which is the best?
According to Jami Counter, who charts premium economy sections for TripAdvisor's SeatGuru website, the answer is clear: tiny OpenSkies airline, owned by British Airways.
"It's a step up from any premium economy product," he said.
Notably, OpenSkies' premium economy seats are spaced 47 inches from the seats to their front and back, more than any other airline. At 20 inches wide, they also exceed the industry norm. Unfortunately, OpenSkies has just one U.S route, from Paris Orly to Newark.
Counter is also bullish on Air New Zealand's premium economy offering as well as the products offered by Hong Kong's Cathay Pacific, Taiwan's Eva Air, Singapore Airlines and Japanese carriers ANA and Japan Airlines.
"Generally, as a rule, you can't go wrong with Asian carriers," he said.
Second only to OpenSkies in premium economy in legroom is Norwegian, which offers 46 inches between rows. Virgin Atlantic has the widest premium economy seats at 21 inches, compared with a standard width of about 19 inches.
