<div>Is the issue the release schedule? It doesn't seem that way. It seems the issue is lack of authoritative information. Does IATA indeed have a source of authoritative information that isn't public? Or do they do what IANA does in the absence of authoritative
information, i.e., guess? In other words, are we dealing simply with two different guesses that went in different directions?</div>
<div><br class="">
</div>
<div>If IATA does indeed have authoritative information, it would be great if they would share that information (the source material, not just the conclusions).</div>
