You are right, Delta is the only airline that will allow ferrets in the
cabin.  I flew from Puerto Rico to Tampa, via Atlanta with my two ferrets.
You need to make arrangements via phone, rather than the internet as there
are only so many animals allowed on a single flight.  It is now $70, to
take them with you.  And the kennel must fit under the seat in front of
you.  Good luck!
