China United Airlines Airbus A330 Seat MapsChina United Airlines

Passengers seated in business class on A330-300 can expect to enjoy a selection of premium meals and beverages. These are usually vastly superior to those offered in economy class which may not include free meals at all on some flights. You can expect a comfortable seat with more legroom but it may not fully recline on domestic flights.

Depending on the airline, premium economy passengers get extra legroom, extra recline, extra seat width, priority boarding, priority luggage allowances, extra earned miles, amenity kits, larger in-flight entertainment screens, upgraded headphones, and premium meals.

When you purchase an economy class ticket on A330-300, it means you are sitting in the main cabin, and not located in first or business class. Seats are smaller and packed more closely together, and in-flight services are limited. Economy class seats on domestic routes usually have a seat pitch ranging from a very tight 27 to a generous 32 inches (68.5 - 81 cm).
