I would be very surprised if this person was working for an airline which paid its employer taxes in either of the two states mentioned, therefore, an unemployment claim would be likely to be based from the state the airline was in, and subject to its rules. Also, if there was no monetary eligibility there would never have been all these hearings. If you have no claim, there is nothing to appeal to be approved for or denied.
As said, there's very little you can do at this point. And most airline policies are set up so that you are especially during your probationary period, dangling at their complete mercy as far as why they can terminate your employment during this period. It may have been a total and totally unavoidable accident or bad luck that caused you to miss this call in, but if they WANT TO, they can according to their regulations, use this as a reason to terminate you during your probationary period. They don't even have to follow their own policies, if they want to they could've made an exception and not fired you for this.
But the fact you've been working for however long or how badly you need unemployment has very little to do with your receiving it. It is not an entitlement program and is not in place based on your low income or need for it. And also, the people who receive it are not all the low life and undeserving who know just what to say or have lazy employers.
In a heavily unionized industry like the major airlines, they have been doing this a long time, they are very interested, and they take great pains to weed out people during their probationary period who give them the slightest reason to do so, usually without unemployment benefits due to their knowing how the system works and having done their homework quite thoroughly.
