Try again, all the common was wiped out. Why do think the new ticker is AAL?
Tell me how much of the $400m each shareholder got? My guess is a penny in the dollar. Again the stock was worthless and wiped out. Sure share holders MAY have got 400m but how many shares were their? In Chapter 11 shareholders are last to collect if their is anything leftover.

I don’t think you read the entire article because only the investors who bought AMRQ made out not the AMR investors. You need to do your homework.

correction I was wrong I looked it up and they received 3 pennies on the dollar. But the stock was wiped out as it always does in bankruptcy regardless if it’s a 7 or 11. So does AAL have value if they file? you be the judge. If you buy the stock today at $12 and they file mostly won’t receive one cent. Now if you want to buy it in bankruptcy when the ticker will be AALQ you do have a chance to make money like the example you provided above. That’s a very different scenario then the common shareholder who bought AMR vs AMRQ.
