If you want to recline your seat, you’ll have to pay more on WestJet’s newly redesigned planes.

The Canadian airline, which serves 19 U.S. states, the Washington, D.C., area, Puerto Rico and destinations worldwide, is getting rid of reclining seats in standard economy on its refreshed Boeing 737-8 MAX and 737-800 planes.

In all, 43 aircraft will be reconfigured, with the first expected to enter service this month and the rest expected to be completed early next year, according to the airline, which adds that that's less than a third of its narrowbody fleet and includes former Swoop, Lynx and Sunwing planes.

WestJet says the fixed-recline design will help "preserve personal space." In a statement to USA TODAY, the airline said, "Through our guest user testing, half indicated they preferred a fixed recline, to avoid feeling impacted by other passengers encroaching upon their space."

Reclining seats will, however, be offered in new Premium cabins and Extended Comfort seats within economy, on the former all-economy aircraft.

According to a press release, Premium seats will feature "ergonomically contoured seat cushions, reclining seat backs and a large headrest with four-way adjustment capability," like WestJet’s 787-9 Dreamliner aircraft.

Even though standard economy passengers won’t be able to recline, they’ll get new seats with "adjustable headrests and enhanced cushion and back support," in-seat power outlets and personal phone or tablet holders.

Lavatories and galleys are also being updated, and the entire fleet is getting upgraded Wi-Fi service, which is free for WestJet Rewards members.

"The layout for our refreshed cabin caters to our guests’ diverse preferences," WestJet Executive Vice-President and Chief Experience Officer Samantha Taylor said in a statement. "Whether they opt for Premium seating with extra amenities and legroom or for more affordable ticket prices with less space, we’re excited to introduce this range of products for our guests to enjoy."

The airline notes the cost per seat will be reduced in refreshed cabins because "ultra slim-line seats allow enough space on-board to add one seating row compared to the airline’s prior standard layout."

The airline added, "WestJet has always been a pioneer in making air travel available to more Canadian(s), largely through our ability to keep costs low and to offer affordable airfares – to continue to do so, we need to be willing to try new products and see how they work for Canadians."
