Air Busan

Air Busan is the low-cost carrier of Korea's second city, flying from Busan's Gimhae airport across the Korean domestic network and out to short-haul destinations in Japan, Southeast Asia and greater China. Founded on the Asiana side of the industry and now inside the Korean Air group's stable of low-cost carriers, it gives travellers in the country's southeast a way to fly internationally without first backtracking through Seoul, and that regional identity shapes the whole operation.

The fleet is Airbus A320-family throughout and every published layout is a single economy cabin from the first row to the last. What changes between aircraft is density: Air Busan flies the A321 and A321neo in more than one fit, and the difference between the roomier and tighter versions of the same aircraft is real. The published map for your flight is the quickest way to see which one you have drawn.

The published layouts cover the A320, the A321 in two fits and the A321neo in two fits, one of which is the long-range A321LR airframe. All of them run three-by-three economy with no premium cabin anywhere.

The standard A321 is the gentler of its pair; its denser sibling packs several more rows into the same fuselage at a tighter pitch. The A321neo carries the longest cabin in the fleet, while the A321LR takes a different approach for the longer sectors it flies: a slightly easier pitch overall and a block of extra-legroom rows right at the front, the closest thing to a forward cabin Air Busan offers without actually fitting one.

This is a low-cost product in the straightforward sense: the same seat through the whole cabin, buy-on-board catering and quick turnarounds. What you are choosing on the map is position and knee room rather than a different chair, which keeps the decision honest.

The extra-legroom rows do the heavy lifting. Every aircraft carries them at the front bulkhead and by the over-wing exits, and on the denser fits they are the difference between a tolerable sector and a cramped one. Bulkhead rows trade under-seat stowage for the space, exit rows trade recline, and the standard rows in between are much of a muchness, so the sensible spend is on one of the marked rows when the sector runs beyond a couple of hours.

Sit forward if a quick exit matters: boarding and disembarking both favour the front, and the rows at the very back sit against the rear galley and lavatories, where the queue forms. The exit rows carry the legroom but fix the recline, and the row directly ahead of an exit usually loses recline without gaining anything, which makes it the quiet trap on these maps. One numbering quirk: the fleet skips row 13 entirely, so the cabin is one row shorter than the last row number suggests.

The fit matters more than the aircraft type here. Before paying for a specific seat, check whether your A321 or A321neo is the standard version or the dense one, because the same row number can mean a noticeably different amount of space. On the A321LR, the front block of extra-legroom rows is the pick for the longer sectors that aircraft flies.
