Dragonair is adopting its parent carrier Cathay Pacific's long-haul economy seats across the majority of its fleet from March 2013.

The new economy seat features an increased width, “more personal storage space”, nine-inch touchscreen TVs, and USB / iPhone ports, as well as the new Studio on-demand in-flight entertainment system, with over 100 films, 500 TV programmes, nearly 900 music albums and over 20 radio channels.

Dragonair used to have a number of different seats in its economy class cabins, some of which you may still encounter:

The short-haul Airbus A320 offers a seat pitch of 29-30 inches. Seats are 17.5 inches wide and have a five degree recline. There is no entertainment system.
The larger A321 offers a pitch of 30-31 inches and its seats are 18.7 inches wide. Entertainment is via overhead screens and 16 audio channels. Some seats on both aircraft types have 110-volt power sockets. Catering depends on the length of the flight, with either snack boxes or a full meal service with a choice of two mains.

On the long-haul A330, type one has a seat pitch of 31-32 inches, while types two and three have 31-33 inches. All A330 seats are 18 inches wide and have a six-inch recline. Type one aircraft have overhead screens and offer 16 audio channels.  Selected seats have 110-volt power adapters. Type two and three A330s have personal 6.5-inch video screens showing 10 choices of film and offering 16 audio channels. Selected seats have 110-volt power adaptors. Catering on longer flights is via a trolley service offering two choices.
