Arrival day
Requirements without a countdown
These conditions still apply. Choosing an arrival date does not check them.
The cat must appear healthy on arrival and may be inspected at the port of entry.
Fails if: Signs of a disease that can pass to people.
A cat needs no proof of rabies vaccination to enter the United States, but CDC recommends it, and the US destination may ask for more.
CDC does not require a general health certificate, but some states and airlines do.
An export health certificate is usually needed when a pet's final destination is outside the EU. The owner applies for it in DAERA's Export Certification System (DECS).
Apply on DECS no earlier than 10 days before the pet leaves, and at least 2 working days before it is dispatched.
A cat going to Massachusetts travels on GOV.UK's export certificate for cats to Massachusetts.
This plan assumes one air journey, with every step done before you leave. Unless you give a departure date, it assumes you leave the day before arrival or on arrival day. Times are local to the United States (America/New_York).
Which airlines carry cats on this route
The only airline in our sources does not carry cats on this route.
This is what airlines offer. An airline can offer less than the rules allow.
Hold means checked baggage. Manifest cargo is a separate booking, even when the animal travels in the same aircraft hold.
