AA may not have replied to this article but I do think there is some basic diligence required before reporting something. To me, the main assertions in this article do not pass the smell test.
Does anyone really believe that a 3rd party app is "critical to the job" of being a flight attendant? How do you explain planes flying just fine for decades before this app or the phones it runs on having appeared? Is the app approved by the FAA or any part of the endless required industry checklists and reporting? Give me a break. If flight attendants were not able to find their assignments it would be a national story with the FAA involved. It is not.
There is also text describing a manner of workflow assignments that I do not believe has anything to do with reality either. Do you really believe AA is failing to staff flights because it did not hear back from attendants who were waiting to hear which flights their friends might be on, and even if it was, that their only way of contacting their friends was a via an anonymous public third party app? That's not how a railroad (or airline) runs either.
"Off-hours might not accurately describe the ground time of flight attendants since much of it is spent planning their next flight"
This is fairly major assertion which I do not see backed up by any evidence. Are you even able to get a quote from the flight attendant's union making that allegation, let alone the airline confirming it? I believe the implication that flight attendants are required to be either in an airport 24/7 or monitoring an app 24/7 to see if they might be given a random, new assignment at any time is false. My understanding is there are specific windows & flows at which flight preferences can be expressed and at which flight assignments are received, which are understood by the attendants for their airline. Other than paid standby, where you are at the airport so you can reach a gate in minutes if needed, if you are not on the schedule, you are not required to monitor it 24/7 to see if you were suddenly added with no notice. (And duh, because of course such a system would never work.)
"There are no real-time updates on the numerous daily flight delays"
This also bears some digging into. I've gotten these as an airline customer via text and email. General flight tracking is available from numerous sites and apps.
Anyway, I am not a credible airline industry expert either, but they do exist in the world, and this article appears to have a very low signal to noise ratio with no attempt to contact one to improve it. Please exercise at least some independent judgment and critical thinking before taking the opinions of one private developer, not even an airline insider, on how a major industry operates.
On the flip side, without any information at all, I'll easily believe this app has a nicer UI, is more performant, may offer more optional features, or is just simply more preferable to some people than whatever the provided enterprise IT system is. All fine and good to report just that but if you're going to claim this is a critical failure preventing flight attendants from doing their job the standard needs to be much higher.
