Budget Airlines

I don't think Frontier has switched the seat pan style to lower the weight, except as an incidental benefit; they've done it to make the seats cheaper to build. As a PP noted, Frontier's seats now have NO padding; they are only vinyl covers pulled over metal-framed mesh seat slings. This photo, taken from the side, reveals the actual edge of the sling pan showing through the vinyl cover in the economy seat on the left.

I know upholstery; it isn't just the weight of the foam; it's the weight of the extra fabric that goes on the sides and lower surface, and the fasteners that hook the pieces together -- even thread has weight, and an average padded seat cushion uses about 100 feet of heavy-gauge thread, plus 20 or so staples and some glue. Still, all of that probably only equals out to the weight of about 3 grown men for an entire aircraft, though the fuel savings probably does add up over the life of the seat.

What they are really saving is labor/materials cost, and shipping cost from the mfr. to the airline. It's immensely cheaper and faster to sew up a sling seat cover than it is to create a foam-filled upholstered one. Even with my home machine, I can run up a 2 layer sling in about 15 minutes doing them one at a time; factories use computer-driven saws to cut 50 layers of fabric at a time and machines that do 2K stitches per minute, so I'm guessing that sewing them together takes maybe a minute each, as opposed to the 30 minutes or so that putting together all the components of an upholstered foam seat pan will take. It uses a lot less fabric, no glue, and you can probably ship them 60 to a carton, as opposed to about 24 to a carton for foam cushions.

Thinner seats also mean they can place the rows closer together resulting in more rows of seats in the same sized aircraft (i.e. more paying customers).
 

As much as it hurts me to defend any budget airline, they are not cutting cost, it the seat structure….. the seat still have handle like 29Gs in a crash….

Where they save is the padding the foam the have to use is not something you can buy at Joann’s fabrics or hobby lobby….

By using 1 inch and not 4 you can save a lot of money over 180 seats.
Where they save is two fold…
Getting another two rows of seats, plus the weight reduction. If you can cut a thousand pounds worth of foam, the fuel reduction is very noticeable.

Thats part of how they keep cost down, no frills airplane parts…. In this case seats
No frills airplane “parts” ????

*minimal padding*…. Stretch seats a wee bit more.
 
Apparently you haven’t seen the you tube where a mechanic secures a cowling with speed tape….
but you would actually be surprised what can be broken and still dispatch the jet
 
2 pilots having a contest over who knows more. This should be interesting.

So assuming 30 rows of seats, six seats per row, and saving 4#/seat = you're at 720# of weight "savings". BUT, you've now added two additional rows, so that's got to be 240-500# of ADDED weight. So is 500# of weight savings really that much? That's what two adults (with luggage)?

I do not pretend to know the math. Just repeating what the bean counters tell us.

I am a captain for a LCC.

I have seen *most* everything.
The stuff I have not seen would not surprise me.

Depend on the program 181 pounds for an adult….

carry ons and checked bags varies a bit more but say 20 for a carry on and 30 for checked
 
may in an older regional airliner…. Such as the emb 130 /140, or the CRJ 200, no body uses those anymore
Hey now, I've logged 7 segments this year on a CR2, still plenty of them flying in and out of ORD in AA and UA livery under Skywest and AirWisconsin. I don't think there are many left at MSP, which used to have it's own concourse for the Devil's Chariot.
