SEA to BOS
Seattle to Boston Pet Relocation
Dogs and cats fly with us from Seattle to Boston, from your door to the new one. We arrange the pickup, provide an airline crate when needed, take care of the forms and the cargo booking, and arrange the drop-off at your new home.
Moving your pet to Boston
No other option gets a pet from Seattle to Boston faster than a flight: about 5.5 hours airborne rather than days of driving. Pets ride as airline cargo inside an approved crate.
Boston is three hours ahead of Seattle, and the flight takes most of a day door to door. Winters are cold, so a vet acclimation letter is common from November to March, and summer days over 85°F keep pets on the ground. Massachusetts requires a rabies vaccine for pets six months and older.
We look for the flight and time of day that put the least strain on your pet, and we work out the timing with you so a person is waiting at both ends. Airline space, weather and breed rules affect every booking, so nothing is final until the airline confirms the flight.

Airline rules that matter on this route
- Health certificate: any pet in the cargo hold must have one, signed by a licensed vet within 10 days of departure. Details on our vet health certificate for flying page.
- Temperature: as a rule, pets go in the cargo hold only when every airport on the trip has a forecast of between 45°F and 85°F. The dates are in summer heat rules.
- Breeds: the cargo hold is closed to snub-nosed breeds, such as every bulldog, boxer, pug and mastiff, plus Persian and Himalayan cats. The full list is in snub-nosed breeds and flying.
- Size: a limit of 150 lb for pet and crate combined, and crates no bigger than the 500 series. Larger pets get a custom quote. Sizes are on airline pet crates.
- Pickup on time: the airline gives 4 hours after landing for collection, so we plan the pickup before booking.

Entry rules for Massachusetts
Two sets of rules apply: the airline's, and those of the state your pet is moving to. For any pet flying in the cargo hold, the airline needs a health certificate from a vet within 10 days of the flight (14 days for Hawaii). Ask for it from a USDA accredited vet, on an official state form or an electronic certificate, with the rabies vaccine details on it. That one certificate meets the state rules below in almost every case.
- Dogs, cats and ferrets 6 months and older must have a rabies vaccine. A pet moving in without one must get it within 30 days of arrival.
- Check the health certificate rule with the Massachusetts Department of Agricultural Resources before you travel.
