China Eastern Airlines A330-300

Yes. This three-cabin A330-300 carries a dedicated Premium Economy between Business and Economy, with more room, recline and a better service than standard Economy. On the longer routes this jet flies it is a sensible step up short of a full Business fare.

It is a full-flat one-two-one cabin, so every seat reaches the aisle on its own and lies flat for sleeping. That makes it a genuine long-haul Business rather than an angled seat, and one of the better premium products in the widebody fleet. Note the airline flies another A330-300 fit without Premium Economy, so the map is worth checking.

An outer window or aisle dodges the four-across centre block, and the bulkhead rows behind a divider stretch out the most, though a bag rides overhead. The front of Economy loads and empties ahead of the rear rows by the galleys and lavatories.

In the one-two-one cabin the single window-aligned seats are the most private, so solo travellers gravitate to them. Every seat reaches the aisle, so the choice is really privacy and position, with the front rows boarding first and the rear rows quieter.
