I am allergic to Animals, Dogs and Cats in particular and I am trying
to set up travel plans.  I know Southwest has a allergy friendly
policy (they only allow seeing eye dogs).  What other airlines have
similar or better policies?  What contacts can I make and exceptions
will be made to get through customs? (Police Dogs routinely sniff
around airports, so I can't spend too long inside of one)
FYI, the airports I will be looking at are Buffalo, NY; LAX;
Nashville, TN; and Kansas City

Every airline, including Southwest, is required by Federal law to
allow service animals (not just seeing-eye dogs) on their flights.

Most airlines will permit one or two animals in the cabin but they
must be pre-registered.  This would mean the reservations department
can alert you to animals on the flight before you make your
reservation.

Amtrak coes not permit animals to travel in the passenger cars.

Hagan, I understand they have to allow service animals, but I have
never seen a service animal that is not a dog on a flight and they are
quite rare.  I am not as worried about service dogs as I am about
pets, specifically cats.  Service dogs just don't have the frequency
of occurance that pets do so I can expect a flight to be fairly pet
free and the rare occurance be that I get bumped rather than vice
versa.  Actually, I find this law interesting because it is part of
the equal access laws, and makes access to flights for allergic
individuals difficult if not impossible.

Funfest, airlines do not require preregistration of animals in the
cabins if they are small enough and there are not too many on a
particular flight.  This is actually one of my main gripes with the
airlines, and one which does not have an easy work around (basically I
wait until everyone has boarded and then they tell me).  Your comment
on Amtrak is very helpful though... thank you for that.
