Boomer should be WEARING a tight enough Collar that he can't
possibly get it off (or get a paw stuck under it) with
TWO custom engraved Tags:
1) with a "From:" tag with your first initial + last name + phone number
2) with a "TO:" tag with Deb's initial + last name and two phone
numbers - home and cell + city if there's room.
3) Current Rabies Tag

DON'T rely on paperwork on or in the carrier to be his only ID!

And find out WHERE the "Original" Vet Health Certificate and
Rabies certification papers need to be -
shipped with the carrrier/crate or turned in to someone?

You should MAIL copies of ALL his paperwork and flight receipts
and airbills to Deb.

Deb:
Do you know "exactly" where to go to "claim" him??
What building to go to and what TIMES you can get to that building?

Airport CARGO areas have as much or more security than the passenger
terminals do - often with Pass Card or Combination locks that the
truck drives have and no human guards to "talk to".

"Enjoy" the Flight, Boom!
Hope you get a "window seat"!
