So I'm not familiar with this website, but this article is terribly written. First, they don't attribute any of their information. Where did they pull this from?
There's no response from Delta and the author appears to be drawing their own conclusions without any company statement. While they mention they reached out to Delta, they didn't appear to wait for a response.
I'm not defending DL's A220 fleet one way or the other, I'm just saying this is a poorly written article that wouldn't pass Journalism 101.
I think the article is powerful because it actually has data. This is DOT data
The A220 numbers are horrible. The difference between the best (737-900ER ) and worst (A220 ) for Delta is huge!
The comments from Airbus Canada indicating that they are working to get the airplane to 99% technical dispatch reliability indicates how far behind the plane is. Most major A320 and 737 operators have reliability in the 99.4-99.8% range. If the A220 is struggling to meet 99%, that is a problem which will take a lot of money to solve.
The MD-88 looks great in terms of reliability compared to the more modern aircraft. I’m still of the belief that Boeing really missed out by ending the production of Douglas airframes so early after the merger. With DL leasing the 717s from WN, that’s a bigger statement than any purchase of A220s. Very surprised that DL would risk so much on a new aircraft when they pride themselves in being on time.
You have lies, damn lies and statistics. Here are statistics at work.
On paper, 737NG and A32xCEO should have by far the best dispatch numbers as they are a large fleet, extremely mature as an aircraft in terms of all aspects: design, manufacture, airline operational experience, spares availability at the average airport. On the other hand, because of this, they will be pushed to the max and have the most demanding schedules.
The 717 and MD-8x are on the way out. The airctraft is mature, operations and issues are very well understood. The 717 is concentrated in ATL so as long as it is close to ATL, parts will be there. It is higher in fuel consumption as well as being phased out so it will not be maxed out on routes. The overall utilisation will be less than 737/A32x and therefore not as tightly scheduled and a bigger chance to catch up on delays. The data seems to show this, but the interpretation of the data is highly subjective as all details and sources are missing and it fits my interpretation but not someone else's interpretation.
The A32xNEO is partially proven with relatively immature engines. Not as bad as the A221, but not on par either with A32xNEO and 737NG. On the other hand it is the cheapest to fly so will be pushed. Engine maturity and parts availability will be an issue as parts are needed system wide.
The A221 has problems: there are not too many in service so the statistics are less reliable as outliers have a far bigger impact. The plane is new. Air Baltic and Swiss are too small a fleet to get maturity up, and even with bigger volumes it takes years (and blood, sweat and tears) to meet the numbers of the 737NG and A320CEO. The design is not mature, the service network is highly immature, the engines are new and it is a new aircraft for the operator. The numbers would have been bad if this was an Airbus or Boeing brand new aircraft design with less than 100 flying but this is a product from a company which went bust because of the development process. It is a miracle they were produced in the first place. If you look at the production list: https://www.abcdlist.nl/cseries/cseries.html
, then you can see that Delta is more or less the launch customer. Swiss is ok, but they are no Lufthansa. The other airlines listed are not the ones you expect to introduce a new aircraft type and help to get it to maturity. I expect Delta got a good discount for its anticipated problems.
Let's see again in 2 years and see where we are.
