{{Main|Airline seat}}
The types of seats that are provided and how much legroom is given to each passenger are decisions made by the individual airlines, not the aircraft manufacturers. Seats are mounted in "tracks" on the floor of the cabin and can be moved back and forth by the maintenance staff or removed altogether. One driver of airline profitability is how many passengers can be seated in economy class cabins, meaning that airline companies have an incentive to place seats close together to fit as many passengers in as possible.<ref>{{Cite web |last=Abad-Santos |first=Alex |date=17 April 2017 |title="Calculated Misery": How Airlines Profit from Your Miserable Flying Experience |url=https://www.vox.com/culture/2017/4/14/15275642/united-airlines-calculated-misery-dragging-man-off-plane |access-date=6 April 2024 |website=vox.com}}</ref> In contrast, ‘premium class’ seat configurations provide more space for travelers.<ref>{{Cite web |last=Dong |first=Chris |date=24 November 2023 |title=Why Airlines are Investing Big in Premium Seats |url=https://www.afar.com/magazine/airlines-are-investing-big-in-premium-cabins-heres-why |access-date=6 April 2024 |website=afar.com}}</ref>

Passengers seated in an '''exit row''' (the row of seats adjacent to an [[emergency exit]]) usually have substantially more legroom than those seated in the remainder of the cabin, while the seats directly in front of the exit row may have less legroom and may not even recline (for evacuation safety reasons). However, passengers seated in an exit row may be required to assist cabin crew during an [[emergency evacuation]] of the aircraft opening the emergency exit and assisting fellow passengers to the exit. As a precaution, many airlines prohibit young people under the age of 15 from being seated in the exit row.<ref>{{cite web|url=http://www.casa.gov.au/airsafe/trip/seating.htm |title=Civil Aviation Safety Authority – Seating information |publisher=Australian Government Civil Aviation Safety Authority |access-date=18 March 2013 |url-status=dead |archive-url=https://web.archive.org/web/20090303050750/http://www.casa.gov.au/airsafe/trip/seating.htm |archive-date=3 March 2009 }}</ref>

The seats are designed to withstand strong forces so as not to break or come loose from their floor tracks during [[turbulence]] or accidents. The backs of seats are often equipped with a fold-down tray for eating, writing, or as a place to set up a portable computer, or a music or video player. Seats without another row of seats in front of them have a tray that is either folded into the armrest or that clips into brackets on the underside of the armrests. However, seats in premium cabins generally have trays in the armrests or clip-on trays, regardless of whether there is another row of seats in front of them. Seatbacks now often feature small colour [[LCD]] screens for videos, television and video games. Controls for this display as well as an outlet to plug in audio headsets are normally found in the armrest of each seat.
