But aircraft have a useful life of 20 years and more, so differentiating between a 2014 delivery and a 2016 delivery (in the case of VA) does not make sense IMO.<br />But of course you are right: NOT replacing the 757 at all is not an alternative...<br />aeroturbopoweraeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-69946823706988540382011-08-31T18:59:47.795-04:002011-08-31T18:59:47.795-04:00Cant we make the argument that the 737-900ER's...Cant we make the argument that the 737-900ER's that Delta is taking in say, 2014, are competing over the course of their lives with A321's that JetBlue is taking in 2014, and not 321NEO's they take in 2018 (or whenever). Delta is clearly going to be ordering a different type of aircraft for delivery beyond 2018 itself. A true apples to apples comparison would be a 2014 vs. a 2014 delivery, not a 2014 delivery vs. some airplane the competitor gets down the road.<br /><br />Besides, the Opportunity Cost of NOT replacing 757's and such until 2018 or later is far worse than the economic disadvantage implied in the analysis. no?kiran6461https://www.blogger.com/profile/16678828574424921021noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-53361784714737721462011-08-31T04:06:20.943-04:002011-08-31T04:06:20.943-04:00MK2,

The problem Delta will face is that there are airlines that will take the reengined aircaft (both the A320neo and the B737MAX) at the same time Delta is getting their last bactch of B737-900ER and they have to compete with them for the 10-20 years afterwards.<br /><br />aeroturbopoweraeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-81928089126379604302011-08-30T17:01:19.944-04:002011-08-30T17:01:19.944-04:00Hello aeroturbopower,

So I cannot see how this should be biased or outside od reality...<br />As soon as technical data for the RE is available (and I guess we can expect these in the next few weeks as the Boeig board should give it's OK for the RE today), I will try to make an assessment of RE vs. NEO, for sure. Also, it would be interesting to make a comparison of AA's future 737-900RE (I guess they are included in their order) vs. DL's B737-900ER.<br /><br />aeroturbopoweraeroturbopowerhttps://www.blogger.com/profile/17686461923667604678noreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-39376951380851810692011-08-29T21:50:06.021-04:002011-08-29T21:50:06.021-04:00Love the blog.

However, the story is never that simple. I have lost track of where Airbus stands with delivery slots for the NEO but with 1000 on order and at least some EIS risk, it's possible (likely?) that DL wouldn't receive their first NEO (or to a lesser degree RE) until 2020 or later. So, the full analysis would compare ~5 years of NG Vs 757 performance plus ~20 years of comparison to the NEO. Add in elevated maintenance for the old planes and the time value of money and the NG decision starts to look. Pretty good, no? <br /><br />Again, thanks for the blog.<br />MattyAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8118460937928958757.post-29539594644129605902011-08-29T12:35:42.798-04:002011-08-29T12:35:42.798-04:00Correct me if I'm wrong but is this really a v...Correct me if I'm wrong but is this really a valid analysis to compare apples to oranges - an NG to a NEO? Further, Delta wanted to upgrade sooner rather than later and NEOs will not be available in the relevant time frame. Why stray outside of the realm of reality to make a point? Bias?
