The air carrier told the BBC it could realize savings of more than $2.4 million a year by removing all remaining "non-essential" items.
A Ryanair spokesman said the company is also considering asking passengers to carry on their luggage, cutting baggage handling fees. He said, "The order has been made to take out all non-essential items, which include the reclining seats, head rests and window blinds."
The BBC said Ryanair's seats will become non-adjustable, to cut down on replacements needed for reclining models, and there will no longer be a seat pocket, thereby reducing cleaning costs and turn around time.
The Ryanair spokesman also said the airline is considering changes to what type of luggage passengers will be permitted to carry.
Ryanair's chief executive officer, Michael O'Leary, told the Sunday Times: "Most of the space in airports is devoted to baggage handling. It's not just a question of staff. It would mean smaller airports, simpler facilities and lower charges."
