Not the Herald - they had left the fleet by the end of 1966.

Thanks Dave... you always seem to have an encyclopaedic knowledge of these things :)

Certain about most of those types except perhaps the Heron as well (have seen it in late BEA colours)... so down to 9-10 types!

As of 1976...

BA
Concorde (if the types below were all still in operation around 1976 thinking specifically of the Heron)
Tristar

ex BOAC
747
707
VC-10

ex BEA
Trident
1-11
Vanguard (later Merchantman)
Viscount
Heron?

Flash 8, if you nudge forward to 1990, BA had the following types in service:

A320
BAC 1-11
146
ATP
B737
B747 (-100, 200 & 400)
B757
B767
Concorde
Tristar
DC-10

So eleven

I suspect a sometime during the 1970's Aeroflot would be the winner in this category

Blimey, yes!

Alitalia bought anything that flew....................

Ah, yes Aeroflot... silly me... and being in Russia and whatnot :)

If you count the piddly stuff I'd say almost for sure, the main core however must have been the IL-62's, TU-134, TU-154, the latter two flying until pretty recently in fact. Once you add all the foreign stuff they have tried (plenty) and other types (Yaks, IL-86 etc), then surely yes, must be the winner around the turn of the century when the fleet probably was at maximum types.

By the early 1980s Aeroflot had about two dozen types but of course they were organised into various units and departments. The unit that operated the An-2 wasn't the same as that which flew the Il-62. Likewise CAAC in China.

Commercially BA, Air France and Delta seem to have been the most diverse thogh Air New Zealand had quite a range after the 1978 merger, I'd need to check but I remember a lot of types from Islander up to DC-10.

WestJet, (WJA), based in Calgary, Alberta, Canada, operated Boeing 737-type aircraft solely for nearly 15 years of their 1996 start date. WestJet patterned their business model after Southwest Airlines, (SWA), based in Dallas, Texas, U.S.A. WestJet presently has a fleet of 122 Boeing 737's, with another 50 Boeing 737's on order.

Southwest appeared to operate only 737-type aircraft for decades. "One aircraft type" is a major aspect of their business model. Southwest Airlines presently operates 720 Boeing 737's, with another 300 Boeing 737's on order.

WestJet's first non-737 aircraft was a leased Boeing 757, which was crewed by a hired (non-WestJet) crew. Regretfully, WestJet added a couple of former QANTAS ,(QFA), Boeing 767's to their fleet.

Go back a couple more years and you can include this, too:

I guess if you couldn't make RHS on the Trident fleet ("aptitude") this was where you were sent :eek:

As this has the BA logo on the fuselage I assume this must be around '74'-'75 ?

Two Skyliners ( G-AZYW, G-BAIT ) delivered March and April 1973 respectively. Former operated the first service on 2 April 1973 BE8746 Glasgow to Tiree. They replaced Herons so were a huge step-up particularly for the passengers.

Power-to-weight ratio was better than Tridents :)

Seasoned travellers used to bring their own earplugs with them, the Skyvan cabin being particularly noisy.

do the scilly isles S61's count ?
BEA/BA had them for years

BIA only operated Heralds for a number of years.

During the 70s/80s, BA Helicopters also had S-58Ts, Bell 212s and a Jetranger; also eventually WG30s I think. Oh, and Chinooks and S-76s.

Mini thread diversion. Had not appreciated there were so many BA heli types. Which BA CEO fell out of love with the heli business?

When did the HS 748s leave the BA fleet? I know the first ATP arrived in 1989 but not when the Budgies left?

I know they had other types but in Europe if one type was synonomous with one operator Scandi DC9/MD80s must come close. I lived in Stockholm in the 90s and the endless procession of different length DC/MDs was even more striking than BEA viscounts at LHR in the 1960s.

Bit like the Cessna or Piper wings joke that theyw ere all the same but just sawed off the right length for the different models, the MD90 must have come close to being twice the length of the 9-15 .

As for one model companies Air India with just 747s in the 70s-80s?
Linjeflug Now defunct Swedish domestic only flew F28s for a while in the 80s/90s
NLM with just Fokker 50s?

British Airways Helicopters was sold to Robert Maxwell in1986, in preparation for BA to be privatised in 1987

AirTran 717
 

AirTran flew the 717 exclusively for a while.
Not sure when they started picking up their 737's
