Which is the oldest 737 in operation today? I'm asking this because there are 3 732 based in ASU now, two of them from a new airline called Regional Paraguaya.
Here are some pictures and data for this 2 732:
EQUIPMENT: Boeing 737-230
ZP-CAJ
SN: 22124 LN727
FIRST FLIGHT: 12/03/1981
PREVIOUS OPERATOR: LAN CHILE (CC-CQT)

PREVIOUS OPERATOR: LAN CHILE (CC-CDH)

Ok, but now another interesting 732! The third 732 is used by as a charter airplane by a company called DELCAR
Here is some info:
EQUIPMENT: Boeing 737-201
ZP-CAQ
SN: 20211 LN141
FIRST FLIGHT: 23/02/1969
PREVIOUS OPERATOR: ECUATO GUINEANA DE AVIACION (3C-HAC)
OBSERVATIONS: cycles: 92.117

So this must be one of the oldest 732 still flying, 40 years of flying!

Does anyone have stories from this airplanes?

There are some belonging to the Peruvian Air Force which are supposed to still be in operation, or at least air worthy, which date from 1968.

This one here first flew on the 15.10.1968, looks in good condition, but not sure if she still flies for sure.

But I think the one from DELCAR has to be one of the 732s with the highest number of cycles...

Here is what it says about this 732 from DELCAR:
Accumulated 64,408 hours, and apparently the highest number of cycles of any 737 in the world: 92,117.

Also according to airfleets, the one from DELCAR is the 8th oldest 732 in operation. Here are the 10 oldest 732's still active:

1) Boeing 737 - MSN 19077 Airline Air Philippines
2) Boeing 737 - MSN 19424 Airline Peruvian Air Force
3) Boeing 737 - MSN 19605 Airline Westinghouse
4) Boeing 737 - MSN 19707 Airline Peruvian Air Force

Sky King air charter's 737 must be old. I've worked on it a couple of times when it does hockey charters for the San Jose Sharks. Does anyone know how old that one is? It's pretty funny to see the two pilots get off the plane followed by the mechanic on every charter!

What about the Indian Air Force - they seem to have a couple of 732s listed as still active that first flew in Dec 1970 and Jan 1971 (see entries for c/n 20483 and 20484).

The 367-80 (707 prototype) is at the Udvar-Hazy Center. I thought the first 737 was at the Museum of Flight near Boeing Field - where the first 747 currently is.

This is correct. But this method of deduction is not guranteed to work. For example In this case 20209 looks to be the slightly younger aircraft. It first flew on 28 March 1969. But 20211 flew earlier (on 23 February) that year. Their respective Line Numbers of 152 and 141 are a better guide to their respective ages.

Also consider D2-TBI - see Reply 8. Its MSN is 19681, its Line Number 68 and it first flew on 15 September 1968. On the other hand MSN 19556 which was N9050U with UA appears at first sight to be measurably younger. But it actually first flew almost 5 months later on 9 February 1969. It had the more revealing Line Number 129.

Thank you for all the good information.
I'm curious: are the NG 737s designed with the same number of cycles in mind?
They might look similar but maybe changes were made to the structure to make them lighter.
An on the same topic, how does the service life expected from a 737 differ from an A320?

I've read a little bit about a program to extend the service life of the A320, and I seem to remember reading that the design for the baby bus was for a shorter service life than the 737.
Any truth to this? Any information will be welcome.

line 283 and 285 which are 1971 builds are with the Indian Air Force as K3187 and K3186 respectively.
The IAF uses three other 737-200's but much later builds incl a 1982 build. IC actually got several late build 727-200's and as CD. However after the grand merger all 732's transferred to AI Cargo. Last time I flew one was DEL-JAI-JDH-JAI-DEL and frankly, while it is nice and sentimental, I'm glad they've been retired!

Boeing MSNs tell you nothing about the aircraft's age or order of construction. You have to look at the line number following the MSN, usually separted by a slash. An airline might order 25 aircraft at once but scheduled for delivery over several years. I think Boeing assigns the MSNs at the time they're ordered, so the 25th in that order might be built and delivered a few years after one with a much lower MSN ordered by another customer but built much earlier. The line number is the order in which they were built.

I want to say that I'm almost sure I saw a 731 in storage across the street from the Pima Air Museum in TUS a few months ago and I've seen it there for quite some time. I'm not completely sure its a -100 but I've flown a lot on the -200 series and it looks just too damned small to be a -200. It's in white USAF colors IIRC, towards the left on one of the privately(?) owned bone yards as you drive down Valencia Rd eastbound and just past PASM, or to be more exact where Wilmot and Valencia meet.

Yes the 732 was offered very soon after the 731 and almost all customers preferred the slightly longer 732. Apart from a 36 inch fuselage section inserted in front of the wing and 40 inch section behind the wing, they were basically identical. They were intermingled on the production line almost from the beginning. The 731 made it's first flight April 9, 1967 and the first 732 flew 4 months later on August 8, 1967.

I recall hearing this:
Life expectancy for average Airbus: 20 years
Life expectancy for average Boeing: 30 years
Life expectancy for average Douglas: 40 years

Quoting Viscount724 (Reply 38):
The first 732 was delivered to UA one day after the first 731 was delivered to LH.

Wow! Didn't know that. Were they developed at the same time?

Sure, the oldest Airbus is supposed to be 39 this year.
As for Boeings and Douglas longlivity I don´t know if it´s true.

Still a few 732's in daily service around Indonesia, though no real oldies... tropical climate and some local airlines' penchant for bending a/c see to that!

Until recently SJ ( http://www.sriwijayaair-online.com/ ) kept a bunch of the smartest 732's but these are being replaced by later types.
