My Pet Can’t Fly This Summer — Now What?

Published on May 21, 2026

You had a plan. You booked the dates, started the paperwork, and told yourself this move was going to go smoothly.

Then you found out your pet can’t fly.

Maybe the airline flagged a heat embargo on your route. Maybe you have a French Bulldog, and the carrier won’t accept brachycephalic breeds between now and September. Maybe your layover city is sitting at 90 degrees, and that’s enough to ground the whole itinerary.

Whatever the reason, summer pet travel restrictions catch a lot of people off guard — not because they weren’t careful, but because flying with pets in summer is genuinely more complicated than most people realize until they’re already in the middle of planning.

The good news is that a grounded flight doesn’t have to mean a grounded move. There are real options, and the right one depends on your pet, your route, and your timeline.

Here’s how to think through it.

Why Summer Makes Flying Harder for Pets

Before getting into solutions, it helps to understand what’s actually causing the problem, because it’s not always one thing.

Temperature limits are strict and apply to the entire route. Most airlines won’t accept pets in cargo if temperatures exceed 85°F at any point along the itinerary, meaning your origin airport, any layover cities, and your destination all have to clear that threshold. One hot stop can block an otherwise workable route, even if the flight itself is fine.

Some airports are off-limits entirely during the summer months. Certain carriers restrict pet cargo to, through, or from specific cities — like Phoenix, Las Vegas, and Palm Springs — from May through September, full stop. If your routing passes through any of those, it doesn’t matter what the forecast looks like.

Brachycephalic breeds face a much higher bar. Short-nosed dogs and cats (Bulldogs, Pugs, French Bulldogs, Boxers, Shih Tzus, Persian cats, and others) are already at higher risk during air travel due to their airway anatomy. In summer heat, that risk increases significantly. Many airlines hold embargoes on these breeds between April and September. If your pet is on that list and your move falls in that window, cargo is likely off the table.

Demand is high, and pet space is limited. Even when weather and breed restrictions aren’t a factor, summer is peak travel season. Airlines limit the number of animals per flight, and that space fills up. A flight with plenty of human seats available can still be fully booked for pets.

None of this means your move has to wait. It means the path forward looks different from what you expected.

Option 1: Reroute Around the Problem

Sometimes the issue isn’t the season,  it’s the specific routing.

If your original itinerary passed through a restricted airport, changing the route might open things up. A more direct flight that avoids a high-heat layover city, or one that departs early in the morning before temperatures climb, can sometimes meet the airline’s requirements when the original route couldn’t.

This isn’t always possible, especially for international moves where routing options are limited,  but for domestic relocations or moves with some flexibility on departure city, it’s worth exploring before ruling flying out entirely.

One important note: don’t try to sort this out through an airline’s general customer service line. Front-line agents often don’t have full visibility into live animal policies, seasonal restrictions, or cargo availability. Go directly to the airline’s cargo or live animal department and get the answer in writing.

Option 2: Ground Transport

For many summer moves, especially within the U.S. or across borders into Canada or Mexico, ground transport is not a fallback. It’s genuinely a better option.

A professional pet ground transport service moves your pet by vehicle with regular rest stops, consistent temperature control, and hands-on care throughout the journey. There are no heat embargo thresholds to worry about, no cargo holds, and no layover cities. Your pet travels in a climate-controlled environment with someone checking on them directly.

This option works particularly well for:

• Brachycephalic breeds that face airline restrictions in summer
• Older pets or those with health conditions that make air travel riskier
• Moves along major corridors like the East Coast to the Midwest, Southeast to Texas, U.S. to Canada, where the drive is long but manageable
• Pet parents who want more visibility and peace of mind than cargo allows

Ground transport does take longer than flying, but for many pets, the lower-stress experience more than makes up for it. A dog who would have spent eight hours in a cargo hold might spend the same time in a van making regular stops — which is, for most animals, a much better day.

Option 3: Adjust the Timing

It’s not always what people want to hear, but sometimes the most honest answer is: wait a few weeks.

If your move date has any flexibility, pushing a departure to late September or early October can change the picture entirely. Temperatures drop, embargoes lift, and airline options open back up. For brachycephalic breeds especially, moving outside the April–September window makes a significant difference in what’s possible and how safely it can be done.

This is worth having a real conversation about — especially if your move is being coordinated around a job start date or housing transition. A few weeks of flexibility on either end can be the difference between a stressful scramble and a smooth move.

Option 4: Pet Nanny Service

If your pet is small enough to travel in the cabin, a pet nanny service is worth knowing about.

A pet nanny is a trained travel companion who accompanies your pet on the same flight, in cabin, not in cargo,  handling the logistics, the check-in, any transfers, and the care your pet needs throughout the journey. For eligible pets, this option sidesteps many of the cargo-related heat restrictions entirely, since cabin conditions are more controlled and the pet remains with someone at all times.

Not every pet qualifies (size and breed limits apply, and availability depends on the route), but for small dogs and cats on international or long-haul moves, it’s one of the better summer solutions when ground transport isn’t practical.

What to Do Right Now

If you’ve just found out your pet’s summer flight isn’t going to work, here’s where to start:

Don’t rebook anything yet. Before you make a new reservation, understand why the original plan fell through. The reason matters. A heat embargo, a breed restriction, and a routing conflict each point toward different solutions.

Talk to someone who knows the specific rules. Pet travel policies vary by airline, route, breed, and season. Getting accurate information from a source that actually specializes in this, not a general call center, will save you a lot of time and wrong turns.

Build in flexibility. If your timeline allows it, having two or three backup dates gives you options. Summer schedules shift, temperatures fluctuate, and a small amount of flexibility can open up routing that wasn’t available before.

Think about what’s best for your pet, not just what’s fastest. A summer move that gets done in a rush isn’t better than one that takes a few extra days or weeks and goes smoothly. Your pet will thank you for it.

We’ve Seen This Before

Every summer, families hit the same wall. A flight that looked fine on paper turns out to have a heat embargo, or a breed that wasn’t on anyone’s radar suddenly can’t fly until October.

At WorldCare Pet, we plan around these situations every year. That means knowing which routes work in summer heat, which airlines are more flexible, and when ground transport or a pet nanny is genuinely the better call — not just a workaround.

If your summer move has hit a complication, we’re happy to talk through what your options actually look like.

Frequently Asked Questions

What temperature is too hot for a pet to fly? Most airlines apply restrictions when ground temperatures exceed 85°F at any point along the route. Some carriers set the threshold even lower — Delta, for example, cites 80°F. The rule applies to the origin, any layover cities, and the destination, not just one airport.

Can brachycephalic dogs fly in summer? Many airlines hold embargoes on short-nosed breeds between April and September. Even outside those months, brachycephalic dogs require more careful planning due to their higher risk of heat-related breathing issues. If your dog is a French Bulldog, Pug, Bulldog, or similar breed, speak with a specialist before assuming air travel is an option.

Is ground transport safe for pets in summer? Yes — for many pets it’s actually the safer summer option. Professional ground transport keeps pets in climate-controlled vehicles with regular rest stops and direct care throughout the journey, avoiding the heat exposure risks that come with cargo loading and layovers.

What if I can’t change my travel dates? If your timeline is fixed, the focus shifts to finding a route and method that works within those constraints. That might mean a different airline, a different routing, ground transport, or a pet nanny for smaller pets. A specialist can help you figure out what’s realistic.

How early should I start planning a summer pet move? Earlier than you think. Summer adds variables that take time to work around — rerouting, ground transport logistics, and documentation timing all require lead time. If you’re moving between May and September, start planning at least 6–8 weeks out, more if your destination has strict import requirements.
