FDX jumpseat guy is the reason this happened....despite FE chiming in...all the work on this was done by RO.
He can explain the details, as we have a ways to go and not everyone is on board yet. Definitely worth an email to him.
It has been allowed for 2 years, but the ops specs needed to be updated and aggreements set up.
Kudos to Rich on this, as it wouldn't have happened without his hard work.
