Once again, how is that effectively different than AA and especially UA? ...each of whom have some 20yr+ aircraft that aren't going anywhere in the next few years either.
They aren't buying more than a couple of used aircraft whereas DL has entire fleets brought used. And what other than a few A319s does AA plan to keep for 20+ years?
What "entire fleet" of model has DL bought used?
Um, you realize that AA has no intention of replacing its 77Es any time soon, some of which are already hitting 20.
Do you also now realize that DL's A32x, MD88s, MD90s, and 717s already have replacements on order and being actively delivered, do you not?
AA may change its spots . . time will tell.
As for DL, all 717 S are used. The CSeries will not replace the 717 for the next decade, it is for shifting more flying to mainline, and some replacement of MD80s where support issues have made replacing them critical.
The MD90s were brought used except for the first 16. Although DL is not inducing any more MD90s, they are not going away anytime soon, as was discussed ad nauseam regarding the V2525-D5 overhauls in Christchurch.
With 752s, of the 111 still flying. 25 were brought used.
767s have been aging out. So before when there was over 70 763ERs, close to 20 were used. Now all that remain is 7 ex-Gulf Air planes.
Gotta go, will do the A320s later. But you should get the point - DL is in a league of its own regarding purchasing used aircraft for revenue service. Even those approaching 20 year old AA 77Es and the older UA 77As have been with one airline their entire careers. Not that UA and AA won't buy used aircraft but it's onesey twosey for them.
