How to say "seating" in Japanese

• 座席ざせきJLPT N3approx.Common
  nounThe straightforward word for a seat or seating in a public place, especially with assigned seating, as on a train, in a theater, or at a venue. Choose this when you mean the seats themselves.
  鞄かばんを座席ざせきの下したに置おいてください。↗

  Stick the bag down under the seat.
• 収容しゅうようJLPT N1approx.Common
  noun, suru verb, transitive verbMeans accommodating, taking in, or housing people rather than seating itself; 'seating capacity' contexts are a marginal fit. It is really about how many people a place can receive, so it is seldom the word you want for seats.
  このホテルは５００人にんの客きゃくを収容しゅうようできる。↗

  This hotel can accommodate 500 guests.

Use 座席 for actual seats or seating in venues and transport, and 収容 mainly for the capacity of a place — how many people it can take in — not for seats themselves.
