Tara,
 
The following airlines in my experience have been the best way to
transport via air.  I have flown these airlines with the ferrets and also
without them.  I have never had problems with these airlines.  I do not
recommend Delta or Continental since I have flown both of these airlines
and had ferrets with blown ear drums as they did not pressurize the
cabins properly.
 
Northwest Airlines 800-692-2746
US Air Airlines 888-300-0099
United Airlines 800-282-2746
 
These numbers are for flying them without a passenger.  Also I am not
sure but you can also check out Midwest Airlines which is the best
airline I have heard of and used.  Of course the ideal would be grand
transportation but sometimes that too can stress a ferret out beyond
belief.  A move is stressful o n a ferret no matter the transportation.
