I’ve stolen the below analysis from Qrewroom. I haven’t checked the numbers but have no reason to doubt their accuracy:
In 2002 the Qantas jet fleet composition was :
B744: 25
B747: 8
B767: 29
B737: 48
A330: 2 ( Mainline Total: 112)
Bae146: 17
B717: 14
Total: 143
Fast forward to 2021 and the Qantas Group jet fleet consists of:
A330: 28
A380: 12
B737: 75
B787: 11 (Mainline Total: 126)
JQ
B787: 11
A321: 26
A320: 53 (+Asia/Japan) 42
NatJet
B717: 20
Network
F100: 17
A320: 6 (+5)
EFA
B737: 5
B767: 1
A321: 1
Total 308.
So in 18 years Mainline has progressed from 112 to 126, and the Qantas Group has moved from 143 to 308.
Now Alliance E190: 3(+12)
Sobering stuff
