On Which Model (If) Did The 737 Stairs Stop?

Sat Oct 18, 2008 4:32 am

I'm wondering if anyone can tell me if newer 737's, 737,738,739's or previous versions have the airstairs built into them under the forward boarding door. If not which model was the last to receive this modification or is it airline specific?

Boeing offers BBJs with a forward airstair option.

Here's a link:

I don't know if any airlines have airstairs installed in their 737NG fleet.
Is it broke...? Yeah I'll fix it.

At SWA, our first three 733s had them, but the rest of our -3H4s didn't. Some of 733s that we obtained from other sources had them. None of the 735s or 737s have them.

Then again, I've heard that some other airlines with Classics and/or NGs have airstairs on theirs, so if so, I'd reckon that it's an option with Boeing.

It's still an option.

All their aircraft have airstairs, as far as I know.

Despite having the rear (ventral stairs) on the 727 having the forward stairs would have been quite handy at times just for the extra weight up front.

She was rather tail heavy, especially when lightly loaded.

I think it is a option, as Easyjet have them with their 737-700's and Ryanair and Thomson on some of their newer 737-800's.

While you are talking airstairs,
The first ten BA A320 delivered in 1988 had fwd airstairs fitted. They were later removed. Does any other A320 series aircraft have them? Our later A319 still have a blank fitted where the door should be.

To your original question, I know they were standard on 737-100/200 aircraft. I THINK they were standard (but a delete-able feature) on classic -3/4/5 aircraft (hence Southwest doesn't have them).
I KNOW that they're now an OPTION on the -NGs. Ours don't have them, and neither do Continental's. I don't know about AA or DL, but I suspect they don't. They're a great feature if you do a lot of hardstand ops, like Ryanair does. But most carriers in the US wouldn't dream of actually letting you out on the ramp. They'd rather you sit in the plane for 1.5 hour while a gate opens up!

I know NB and DM had them at some point on both the classics and NG's but they have been removed and placed in storage.

I believe the air stair is standard equipment on the BBJ’s, these airplanes are designed for the corporate jet market and as such they fly into airports that do not have airline service or have available a mobile air stair.

Its optional.but considering the weight saved,its not worth keeping them on the aircraft.

That really depends on what you're doing with them. Given Ryanair's extremely detailed operations planning, the mere fact that they continue to get them pretty much proves that they're worth their weight, if used in the right operating environment.

The 737-type of forward airstairs must have been optional on 727s although I don't think they were common. If memory correct, CP Air's 4 727-100s had them.

Ryanair flies to a lot of airports with no jetways. They also do really fast turnarounds so the airstairs probably save a few minutes as opposed to waiting for a ground stair.

However, if someone is wating with a set of stairs to push up to the aircraft when it arrives, I think it's a little faster than waiting for the 737 airstairs to extend and the handrails connected at the top. However, using portable stairs requires ground staff who have to be paid, and the airports no doubt charge for use of the stairs (unless the airline supplies them), and Ryanair no doubt prefers to avoid those expenses. With the airstairs they're self-sufficient.

How many Ryanair flights use jetways/bridges at any of the airports they serve? It must be very few, if any.

The B737 airstair has Auto & stby modes & can be operated from within & outside the aircraft...Only precaution is the safety features in the stby system is bypassed so store the handrails before flipping the stby sw.  Smile

It depends on the area of operations.

Probably the weight carried & usage overrides the cost of hiring equipment for Ryanair.

IIRC, at AS, N786AS had the airstairs. I dont know if they are still on that aircraft or not. I don't think we ever used them.... The aircraft was not originally delivered to AS.

Miami Air (LL) here in the states also has the forward airstairs on their 737NGs.

All our B737 Freighters have got the Fwd Airstair removed for obvious reasons & thats a huge weight saving.

I've posted this some years ago when this topic came up before, but some of the earliest 737's also had integral (I think they were optional) aft airstairs. I don't remember if any of the -200's had this feature as an option. They were quite heavy if I recall, and rarely used in CO service.

I think all the 737-200C combis had the rear airstairs, at least those that flew (and several still fly) in Canada. Resolute Bay (YRB) where the bottom photo below was taken is the most northerly airport in North America (74 deg. latitude, about 900 nm from the North Pole) that's ever had scheduled jet service. The runway there is gravel.

Airstairs are only useful at airports with no other available facilities. Down in JER we see BA 737s with and without integral airstairs. The a/c with no airstairs always have the pax disembarking in a quicker time compared to those with integral airstairs which take a good few minutes to deploy and secure (especially as the CC have no idea how to work the handrails most of the time).

WW have removed airstairs from all of their aircraft due to the extra weight they carry (about 200kg IIRC).

Integral airstairs also go tech a lot... its not uncommon to have an a/c nicely boarded on time only to have the stairs sticking out the side of the plane refusing to move inside. Engineer anyone?? No he's having his tea break. Au revoir on time departure!

Quoting JER757 (Reply 26):

That's not entirely true. Ryanair uses the airstairs at airports that have jetways all the time, primarily for cost reduction I think.

Quoting JER757 (Reply 26):

Also not true, *if* you stick a mobile airstair on the back door as well. Having two active passenger doors speeds up unloading/loading a lot more than the time lost to deploying the airstair. This typically isn't practical at airports with jetways because 1) they don't have as many mobile airstairs and 2) you'd have passengers coming out into to different places in the terminal.
