For a summer international move, you should start the pet shipping process 8 to 12 weeks before your travel date. Summer heat triggers airline climate embargoes, cargo space fills quickly during peak relocation season, and health certificates plus import permits often have strict validity windows that must align precisely with your flight date.
Why summer timing is especially tight
Summer is the busiest season for pet relocation because it overlaps with school-year transitions, military PCS orders, and corporate relocations. At the same time, most major carriers impose seasonal live animal embargoes when ground or tarmac temperatures exceed roughly 85°F (29°C) at any point in the pet's journey, including layovers.
The realistic planning timeline
A well-run relocation timeline generally breaks down like this:
- 10-12 weeks out: Confirm destination country import requirements, select an airline route, and get a quote from a professional shipper.
- 8-10 weeks out: Book the cargo or excess-baggage reservation, begin crate training, and schedule required vaccinations.
- 4-6 weeks out: Complete the veterinary health certificate, request USDA APHIS endorsement if traveling from the US.
- 1-2 weeks out: Final vet check, confirm crate meets IATA Live Animals Regulations sizing, reconfirm flight and embargo status.
- 48-72 hours out: Finalize health certificate, complete any last microchip or paperwork checks.
Companies that manage this full timeline as a service, such as Starwood Pet Travel's international relocation program, typically build these deadlines backward from your move date.
Country-specific lead times that can force earlier booking
Some destinations require far more than 12 weeks of lead time. Australia, for example, has one of the strictest import processes in the world — operators like Jet Pets' overseas pet travel service frequently advise clients moving to Australia to start the process 4-6 months out. The UK and EU are more forgiving under the pet travel scheme but still require a rabies vaccination at least 21 days before travel, which UK specialists like PetAir UK coordinate closely with each country's entry rules.
What happens if you book too late
Late bookings during summer commonly result in paying premium last-minute cargo rates, missing a rabies titer test window, getting caught in a heat embargo with no flexible rebooking options, or being forced onto a red-eye or early-morning flight to avoid daytime tarmac heat.
Can I still book pet shipping just 3-4 weeks before a summer move?
It's possible for simpler routes with fewer import requirements, but you'll have limited flight options and higher risk of last-minute embargo disruptions.
Do all countries require a rabies titer test?
No, but many rabies-free or rabies-controlled countries (including Australia, the UK, and Japan) require it, and the blood must typically be drawn at least 3 months before entry.
Does booking early guarantee my pet avoids a heat embargo?
No — embargoes are set close to the travel date based on actual forecasted temperatures, but early booking gives you flexibility to rebook onto a cooler time slot if needed.
