How many seas are there in airplanes?

In aviation, the term "seas" typically refers to "seats," and the number of seats on an airplane can vary widely depending on the type and model of the aircraft. Commercial airliners can have anywhere from 50 to over 800 seats, while smaller regional jets may have fewer than 50. The configuration can also change based on airline preferences, including the arrangement of economy, business, and first-class seating.
