However much I hate AF on the ground, I would have to concede that they have not done too badly financially in recent years. They certainly coped with 9/11 much better than most European carriers.
To (not
)answer the original question, I do not think that AF is quoted on any of the mainstream US exchanges. Shares (presumably ADRs), however, appear to be available on the OTC market (ticker: AIFRF)
If it is for analysis purposes, however, you might as well look at the underlying shares on the Paris Stock Exchange, as ADRs follow the underlying share.
The million-dollar question, of course, is how they will digest the merger.
