We all know that Emirates has operated all variants of the Boeing 777 at some point in history. What are some other airlines that have operated every variant of a type?
For consistency sake (and to keep things interesting), an ER/LR/Neo is each considered a different variant. A different MTOW (242T A330) is not considered a different variant, nor is a fixture such as a sharklet. The A32X series is considered one type, otherwise we'd have a long list for the A319, 20, and 21. In addition, since there were so few A320-100s and A321-100s, we'll consider those the same variant as the -200. Finally, we will not include variants that have not yet entered service (A338, B777X, A19N). Orders for in-service are included.
Just after minimal research (I don't have a ton of knowledge of the A300/A310/707/727 so help me out there too):

Obviously this list can change drastically depending on how you group aircraft. Also obviously only included major A&B aircraft. Feel free to add to the list!

Add Thomas Cook UK to the 757 list, it had (has?) 2 753s as well as their numerous -200s.

Technically you should split this out in two series, one for the 737-100/200 and one for the 737-300/400/500. The 100/200 is known as the original 737 and has been in production from 1966 to 1988.

During the time the 737-300/400/500 series were produced and even some time after that they were called the "present generation", although now they're known as the 737 Classic (unlike the 100/200 series which are known as the 737 Original). They have been in production from 1984 to 2000.

It was logical that after the present generation came the next generation. Luckily you did separate that into it's own category.

Right, I debated with myself how to handle the early 737s. I agree, in hindsight it would have made sense to split the Jurassic and Classic Series.

Similarly, I have absolutely no idea how to handle the DC9 family, which you could argue goes from DC-9-15 all the way to DC-9-95.

At a point Sriwijaya Air of Indonesia simultaniously operated 5 series from 3 generations of 737: -200, -300, -400, -500, and -800.

Varig flew 732,733,734 and 735.

Air France flies A318-21

And to add to the A330: GA is the only operator of the Trent 768 powered variant(A330-341)

IMO, if we're going to split up the 737 family into Original/Classic/NG/Max, then we should split up the DC9 families similarly.

DC9 Original family: DC9-10/20/30/40/50
MD-80 family: DC9(MD)-81/82/83/87/88
MD-90 family: DC9(MD)-90/95

Right but not any neos.

Not sure if this counts, but Aeroflot did more or less have every civil airplanes build in the Soviet Times, so basically also all certified variants of aircraft, that have had various versions like:
Tu-134, Tu-134A, Tu-134A-2, Tu-134A-3, Tu-134A-5, Tu134B
Tu-154, Tu-154B, Tu-154S, Tu-154B-2, Tu-154M

Did any airline operate ALL variants of the BAe *AND* Avro? I haven't found any so far, but some did at least operate either all Avros or all BAes:
WDL Aviation: BAe146-100, -200, -300 (bonus points for -300QT)
Malmö Aviation: Avro RJ70, RJ85, RJ100, also Bae146-200
Flybe: BAe146-100, -200, -300 (bonus for -200QT)
Cityjet: BAe146-100, -200, -300, also RJ85

WF operates all versions of the Dash 8 .

If 737MAX is separate, I'd say the A320neo series should be separate as well...

There are a few airlines already that operate both the A320neo and A321neo, including BA, F9, NK and WW.

If you consider the 741 and 742 is being only one variant (they very much look alike, don't they) then you can say Korean has flown all 747 variants.
Korean has flown the 200. the 300, the SP, the 400 in both the pax and the freighter version, and the 8 in both the pax and the freighter version.

No love for Embraers?
E135, E140, E145: Both American Eagle (now Envoy) and Chautauqua Airlines are the only two that ever operates all 3 variants. ExpressJet doesn't have any ERJ-140, Airlink has no ERJ-145, etc.
E170, E175, E190, E195: LOT Polish Airlines is the only operator that operates all 4 variants.

I didn't consider the different variants of the ERJ (i.e. ERJ145ER, LR, XR, etc. just to start) as it just get way too complicated. Plus the number of airlines that operate all variants are small enough to begin with.

For CRJ:
CRJ100/200: Air Canada, LH Cityline, and Skywest operated both variants
CRJ700/900/1000: None. Of the 4 CRJ-1000 operators, HOP! (BritAir) doesn't have any CR9, Air Nostrum and Arik Air doesn't have any CR7, and GA only operates CRK.

So does British Airways.

Just found out that Malev operated all variants of the 737 classic (300/400/500). As a bonus they also operated the 737-200. They also almost operated the entire 737NG-series, only the 900 is missing.

200:
300:
400:
500:
600:
700:
800:

KLM operated all Douglas types, except the DC-1, but only one DC-1 was build and it was more a prototype for the DC-2

I would be very surprised if KLM didn't operate all civilian fokker planes.

737 NG (B736, B737, B738, B739, B739ER)(Leaving out the 737-700ER. Sorry NH)
-none- (ZH, MA, 9W, LY, KL, TK, AS, CO/UA, DL all missing the 736)

KLM also misses the 739ER in that regard.

I think that Frontier Airlines also falls into that category (minus the 900 as well) before their demise.

That's right. And they were the only ones in the world to fly the DC-5, a very rare aircraft. Plus they were the last ones to fly the MD-11 in passenger version. Yes, KLM has a long history with Douglas and eventually Mc Donnell Douglas. It surprises me, however, that KLM didn't buy the MD-80, like Alitalia, SAS and Finnair did, given their long affiliation with Mc Donnell Douglas and their experience in operating the DC-9.

Just a note: the 787-10 is B78X, not B78J.

As for Emirates, they have also operated the freighter B777.

KLM misses more. They also never flew the 737-500 and 600. They never had the 737-200 in their own fleet, but had it on lease from Transavia.

The original poster is talking about the NG-series, the list is not about the total 737-series..
He stated that they miss the -600 only, but they also miss the -900ER
-200 is a jurasic and the -500 a classic.

Pan Am operated the A300 B4 (but not the -600, or the B2) and the A310-200 / A310-300 simultaneously.
Lufthansa operated all variants of the A300 (incl -600) and the A310-200 / A310-300. <- probably qualifies for the OP criteria
Air France operated all variants of the A310-200/300 and the A300 B2 & B4, but never the -600 variant.

Airlink (South Africa) did operate two E145s a few years ago (leased from Solenta), so they had all 3 at the same time at some point.

Yes, exactly the type of thing I was thinking about.

Thai and Singapore also flew both the A300 and the A310.
Thai flew the A300B4 and the A300-600. I know they flew the A310 but not sure if it was the 200 or the 300 they flew.
Singapore flew the A300B4, not sure they flew the A300-600 but they did fly the A310 both the 200 and 300 variants.
Note also that Thai and Singapore have bought all the Airbus widebodies, besides the A300 and A310: the A330, A340, A380 and A350. And they were among the few airlines in the world to fly the A345.

For the A320 CEO Family, Air France, Avianca, British Airways and Frontier operate or operated all the models (A318/A319/A320/A321).
Being more specific, only Air France really operated all the variants (A318-100, A319-100, A320-100, A320-200, A321-100, A321-200). British Airways is only missing the A321-100.

In other words they didn't fly all variants.
LH is the only airline to have operated the A300 B2, B4, B4 600, A310-200 & A310-300.

G4 operated every version of the MD-80 at the same time at one point. I believe they are the only airline to have operated every MD-80 variant in general.
