Overhead Bin Dimensions

Tue Jan 24, 2012 5:01 am

With the DL/NW merger, I have now found that overhead bins seem to vary greatly between planes - not just from one type to another, but between the old NW planes and the old DL planes. Now that they are getting strict on baggage rules, I was wondering about the differences in overhead bin sizes. I would have thought that all planes from one manufacturer would have the same bin, but this is obviously not true. How many bin differences are there? Is there a comprehensive list of bin dimensions? How about cutaways - bins are obviously not perfectly rectangular - if there were clear dimensions for the various bins would it be possible to design a bag shape that maximized use of the bins while still allowing luggage to be easily put in and taken out?

At a minimum, most new bin designs facilitate a 22 inch roller long direction inbd-outbd.

There are quite a few bin configurations and options. The original manufacturer likely has different options. Additionally there are aftermarket retrofits to increase the size of the bins. I believe there are 4 different sized bins on the 737NG that come new from Boeing. I think they range from fitting 50 to 100 full size carry on bags on a 737-800 depending on the bins.

In general there are many different sized bins and even when getting on the same plane, you don't know what you will find on an airline with such a diverse fleet as Delta. They have 757s that were ordered and customized by 4 different airlines. On top of that some have been retrofitted with door and bin modifications.

The PMNW 757s still have the original factory overhead bins, while DL installed overhead bin extensions on their fleet well before the merger.

Reposting in hopes of an answer...

I am looking for the actual dimensions of the overhead bins for both the 737/757 and 320 aircraft. I know the 737/757 had a few different styles, I am particularly interested in the classic style.

I am looking to design a custom carry on, and I want it to be able to fit in and maximize the most of the overhead room, so I can fit more in there instead of under the seat.

While the maximum dimensions are rectangular, the back of the bin has a slant. I need ot know what those slants are on the Boeing and Airbus, to slope the top of the bag so it slides into that space.

Thanks!

Even just among the Delta fleet there's too much variation. Besides, no matter how it fits, if the bag doesn't fit into the sizing unit (which is 22" x 14" x 9") at the gate the agent will make you check it, no matter what protestations you might make as to whether it fits or not.

A 22x14x9 will fit, but it leaves a large gap of space at the very back of the bin.I have occasionally been able to stuff something back there, but because of the slope I can't quite make a think laptop case fit. That's why I want to know the dimensions of that back part - I figure I am willing to sacrifice a few CCs of space in my rollaboard to have enough room to fit both my rollaboard and my laptop case in the bin wheels out.

Are there really that many differences? I have not found that many. You have the old style classic with the angular doors and no extension, the same but with the extended bin, and the newer curved (but not sky) configuration that has extended bins. Are there more I haven't encountered?

On 757-200s the back/bottom is rounded and not angular. On the 757-300/737NG the back is angular. The angle and size of the bottom pannel is different between the 737NG/753, A320, and MD-80/90. Bags on the 2 seat side of the MD-80/90 have to be turned sideways and anything more than 22" is taking another passenger's space. The same goes for the old 767-300s and CRJ-700/900 and Embraer 170/175. Shoot, the bins on a 717 aren't even the same as the MD-80/90. 767-400/777 bins, A330 bins, 747 bins all different too. And if the 737-900s come with the Sky Interior, yet another different bin.

22"x14"x9" is what's allowed. Sure, you MIGHT be able to make a bag that fits most bins, but once you get on a plane where it doesn't and have to turn it sideways where a standard bag wouldn't have to be turned you are taking up someone else's space. Don't be a bin hog and just get a regulation sized bag and make life easy on the gate agents who already have to spend too much time arguing with passengers about bags that are too large.

Unfortunately I dont know how to explain this without a picture...

The 22x14x9 is a rectangular dimension that will fit in all bins. Since the bins on most aircraft are not rectangular, there is, by definition, so unused space. Once COULD just try and expand the bag to use up some of that space.

OR, one could actually reduce the bag, for instance creating a slant on the bottom, which allows the bag to nestle into that non-rectangular space at the back of the bin. That in turn opens up a small space at the front of the bin, where a small laptop bag can fit vertically in. If you ever had a smaller bag, one of the 20x8 bags, you may have done this already.

Since the majority of the planes I fly, and in fact most people domestically fly, are the 737s and 757s, I want to optimize for that. If it is a diffe

The new pivot bins that Boeing builds are designed for a bag that is 12”x16”x25”and a 4”corner radius.

The previous generation of bins "big bins" were designed for a bag that is: 10.5”x15”x23.5”and a 3”corner radius on the 737NG and 757.

The original 737NG bins were designed with a bag that is: 9”x14”x22'' with no corner radius and is the same dimension used by the A320. This is the official max dimension for a bag, although when stuffed, many exceed it.

If any of your dimensions exceed 12x16x25, then your bag will not fit in a 777, 787 or 737 pivot bin. Cubic volume wise the pivot bins are smaller than the old shelf bins, but don't have the wasted space that you are talking about.

You can design a bag that uses the wasted space in the back of an old shelf bin, but as more airlines shift to airplanes with pivot bins

In theory, you absolutely could. However, the size limit on your carry-on baggage isn't the bin itself, it's the size-wise bin that the airlines use to check your bag. And they're rectangular. You're optimizing to the wrong constraint.

If bags completely fill the bins you then have no room for all the other stuff people travel with -- coats, purses, duty-free shopping and everything else under the sun. On many routes in cold climates during the winter there's no room in the bins for both bags and bulky winter coats.

That's what I am talking about. A 9"x14"x22" bag in the overhead leaves no room in front of the bag for anything. BUT it leaves a space behind the bag. My current bag is overall 9x14x22. But, the top is taperd down a bit. This reduces the volume of the bag a little, but the tradeoff is that when put in top first, it slides further into the bin. That then moves that extra space to the front of the bin, where I can then try and fit a small bag or jacket. If I can get my bag to slide into that space just alittle better, I think I can actually
