Delta has a pretty diverse one right now and will continue to have one:

737-700
737-800
747-400

767-400ER
777-200/200LR
A319
A320
A330-200
A330-300

Coming into the fleet later on this year:

717-200
737-900ER

Quoting srbmod (Reply 3): 777-200/200LR

Sorry, but I just have to correct that one. It should read

777-200ER/200LR.


Anyway, I would say that all the three majors have quite diverse fleets. It is even more mixed up when you throw in the regional jets operated for each carrier.

DL & AA because of the recent mergers, by default.
Does anybody know why the most recent US A321 was delivered with CFM not IAE which seem to be the case with deliveries over the last few years.

For general fleet size, hands down, the three big Chinese carriers CA, MU & CZ.
From E145s to 747s and everything in between and mix of engine manufacturers too.
The usual 737NG & A320 mix but the A320s are delivered with mix of CFMs & IAEs.
One day its a A320-232; next week its a A320-214. Same with the A321s & A319s.

Quoting carpethead (Reply 5): the three big Chinese carriers CA, MU & CZ.

CZ has to be up there with 18 distinct types

Quoting YVRLTN (Reply 6): CA have 14 types plus the 789 on order (seperate cargo and biz divisions)

In the early/mid 1990s, I recall CA having something like 23 types of aircraft in the fleet.

Also French regional HOP! is offering a wide range of different manufacturer:

ex Airlinair ATR 42-300/-500, ATR 72-200/-500
ex Brit Air CRJ-100, CRJ-700 and CRJ-1000
ex Régional ERJ-145, EMB-170, EMB-190

For a regional carrier quite a challenge!

So we could conclude that the fleet mix of SAS is not that bad? A333/A343/A321/A319/MD82/734/736/737/738/CRJ900.

What about Lufthansa?

Add the A320 to that list too.

As AF-KL are actually one airline (like DL) the fleet will be (including britt, city, regional, martinair):

Avro RJ85

You have to distinguish between Lufthansa Group (LHCargo with the MD11F, Cityline with the ERJ's and CRJ's, add then the A332 of SN, and the 777, 767 and F100 of OS, etc.) and LH itself.
LH only has only A380, B748, B744, A346, A343,A333, A321, A320, A319, B735, B733 (did I forget one?)

It strongly depends on the point of view.

We at R3 currently operate:

An-24
An-140
Tu-154
B-737-700
B-737-800
B-757-200
SSJ RRJ-95B
Dash 8 Q400

All of those make up a fleet of 27 aircraft.

I think that it is very easy for the large/mega carriers to have highly diverse types in their fleets. With the wide range of routes they operate they require diverse aircraft.




A better question may be which carrier operates the most diverse fleet in realtion to its overall inventory size?
UTAir may be a good candidate in this field.

I previously worked for an airline that 12 years ago had a total fleet of less than 42 a/c:
A333...A332...A321..A320..B737-400...B737-500...Bae146...FK50.....most of any 1 type was 6 I believe.

I think this could be economical if you outsource literally everything. Training, maintenance etc. If you do things in house I can't see how it would make sense. Fleet commonality is a big plus for JetBlue and Southwest if you ask me. IT doesn't have to be 1 type but if its 3-4 it makes a big difference I think.

For a good overview of domestic fleets see April 2013 issue of Airways Magazine for U.S. Major Airlines Annual Survey. Not much diversity in domestic companies. Airbus, Boeing, Douglas and Embraer and Bombardier for feeder fleets.

Remember Kingfisher? They wanted "five of each".

If we take Austrian separately, they had/have a bit of everything that flies:
736, 737, 738, 319, 320, 321, 772, 763, F70, F100 for a very modest total number of planes. Lufthansa's bosses have grown lots of grey hair in thinking how to deal with this mess. The only time I've been in Vienna in 2010, I saw six different types of OS at six gates in a row. That is something.

This is way back, but when I hired on with DL in '71, I believe we had 173 a/c in the fleet.....

Within a couple of years, the L-100 and CV880 was gone and we had added in the 727-95, 272-295, FH227 and more 9s, thanks to Northeast. We also added in the DC-10 and L1011. By the end of the 70s, the only widebody left in the fleet was the L1011.

Thanks, I thought that all of the CFM birds had been delivered by last year. All 12 A321's that the west fleet recieved in 2012 were V2500 powered.

don't forget the one example of SAAB2000 used for LCY-IOM - or as that's an Eastern Airlines machine maybe it doesn't count.
