Flying with Pets on Passaredo (2Z): What You Actually Need to Know

Hey, I'm Marco. I've flown with my 6kg French Bulldog Mochi on more than a dozen flights, and I've learned the hard way that every airline has quirks—and Passaredo is no exception. Here's what I wish someone had told me before my first trip, plus everything you need to know to fly with your cat, dog, or other pet on Passaredo.

Can My Pet Fly in the Cabin with Me?

Yes, cats and dogs are allowed in the cabin on Passaredo. This is the good news. Your pet travels with you, not in cargo, which means less stress for both of you. But—and this is a big but—there are strict rules about size, weight, and breed.

Here's what nobody tells you: just because your pet is allowed doesn't mean you can book last-minute. Passaredo limits the number of pets per flight, so you need to book your pet at least 48 hours in advance. I learned this the hard way when I tried to add Mochi to a flight 24 hours before departure. Denied. Don't be me.

The Brachycephalic Breed Bombshell

This is where I got hit hardest. If you have a French Bulldog, Pug, Bulldog, Boston Terrier, Boxer, Shih Tzu, or any snub-nosed breed, you need to read this carefully.

Most airlines—including Passaredo—restrict brachycephalic (flat-faced) breeds due to respiratory risks during flight. Mochi is a French Bulldog, and I had to fight to get her approved. Here's the industry-standard restricted breeds list:

  • French Bulldog
  • Pug (all breeds)
  • Bulldog (all breeds)
  • Boston Terrier
  • Boxer (all breeds)
  • Shih Tzu
  • Pekingese
  • Chow Chow
  • Japanese Chin
  • Cavalier King Charles Spaniel
  • Lhasa Apso
  • Shar Pei
  • Staffordshire Bull Terrier
  • American Bully (all breeds)
  • Mastiff (all breeds)
  • Cane Corso
  • Dogue De Bordeaux
  • Presa Canario

If your breed is on this list, contact Passaredo directly before booking. Some airlines allow exceptions with a vet's clearance; others don't. Don't assume. I had to get a vet letter for Mochi stating she was fit to fly, and even then, I was nervous at check-in.

Cabin Carrier Specifications: The Exact Numbers

Your pet must fit in a soft-sided carrier that fits under the seat in front of you. Here are the exact dimensions Passaredo allows:

  • Maximum length: 45 cm (18 inches)
  • Maximum width: 35 cm (11 inches)
  • Maximum height: 25 cm (10 inches)
  • Maximum combined weight (pet + carrier): 8 kg (17.6 lbs)

This is where I made my second mistake. I bought a carrier that was technically within spec, but it was a hard-sided crate. Passaredo requires soft-sided carriers only for cabin travel—they need to compress slightly to fit under the seat. Hard-sided carriers are only for cargo.

Pro tip: Buy a carrier with mesh ventilation on multiple sides. IATA regulations (which Passaredo follows) require adequate airflow. Your pet will be more comfortable, and you'll pass inspection.

The Absorbent Liner Rule (Nobody Mentions This)

Here's what nobody tells you: you must line your carrier with an absorbent mat or pad. Most airlines require this to manage accidents during flight. I use puppy pads or specialized pet travel liners. Mochi has never had an accident in-flight, but I still bring them. Better safe than getting charged for a soiled carrier.

Cabin Pet Fee: 200 BRL One-Way

Passaredo charges 200 BRL per pet, one-way. That's roughly $40 USD (exchange rates vary). This is a fixed fee, not per kilogram. So whether your pet weighs 2kg or 8kg, you pay the same. Book this when you book your ticket—don't try to add it at the airport.

Health Certificate: Non-Negotiable

You need a vet-issued health certificate. This is required by virtually all airlines, even if Passaredo's website doesn't explicitly state it. I've seen people denied boarding without one.

Key details:

  • Validity: 10 days from issue date (some destinations require 7 days—check your destination)
  • Timing: Get it as close to your departure date as possible
  • What it covers: Your vet confirms your pet is healthy, vaccinated (especially rabies), and fit to fly

I get Mochi's certificate 5 days before travel. This gives me a buffer if there are any issues, but keeps it recent enough that no one questions it.

What About Sedation? (Spoiler: Don't)

IATA regulations—which Passaredo follows—prohibit sedation during air travel. A sedated animal can't maintain balance or respond to emergencies. Your vet won't approve it, and the airline won't allow it. I was tempted to sedate Mochi on her first flight. I'm glad I didn't. She was fine, and sedation would've made things worse.

Cargo and Checked Baggage: The Alternative (Not Recommended)

If your pet is too large for cabin, Passaredo does allow cargo and checked baggage transport. But here's what you need to know:

  • Minimum age: 10 weeks (vs. 8 weeks for cabin)
  • Carrier type: Hard-sided, IATA-compliant crate only
  • Water bowl: Must have an attached external water bowl
  • Ventilation: Required on at least three sides
  • Labels: Must display "Live Animals" labels with orientation arrows
  • Temperature restrictions: No travel if tarmac temps exceed 29.4°C (85°F) or drop below -6.7°C (20°F) without a vet acclimation certificate

I won't lie: cargo travel stresses me out. Your pet is separated from you, and temperature control isn't always perfect. Cabin travel is always my first choice.

Advance Booking: The 48-Hour Rule

Book your pet at least 48 hours before departure. Passaredo limits pets per flight. Show up without advance booking, and you'll be turned away. I learned this lesson. Don't repeat it.

Pregnant and Animals in Heat: Not Allowed

If your pet is visibly pregnant or in heat, Passaredo won't accept them. This is an industry-wide standard due to health risks during flight. If you're unsure about your pet's status, call Passaredo directly.

What You Need to Do: Your Pre-Flight Checklist

  • Check your breed: If you have a brachycephalic breed, contact Passaredo now. Get a vet letter if needed.
  • Book your pet 48+ hours in advance: Don't wait. Spots fill up.
  • Get a health certificate: Schedule a vet appointment 5-10 days before travel. Cost varies ($30-80 USD typically).
  • Buy a soft-sided carrier: Ensure it meets the dimensions above. Test-fit your pet at home.
  • Add an absorbent liner: Puppy pads work fine.
  • Confirm your destination's requirements: Some countries have additional import rules. Check before you book.
  • Arrive early: Give yourself extra time at check-in for pet processing.
  • Keep documents handy: Health cert, booking confirmation, and any breed clearance letters should be easily accessible.

Common Questions I Get Asked

Can I bring two small pets in one carrier? Industry standard allows up to 2 small pets in one carrier, but Passaredo's specific policy on this isn't confirmed. Contact them directly to be safe.

What if my pet gets sick during the flight? Inform a flight attendant immediately. They'll document it. Keep your vet's contact info handy for after landing.

Can I take my pet out of the carrier during the flight? No. Regulations require pets to stay in carriers for the entire flight. This is non-negotiable.

What about international flights? If you're flying internationally, your destination country may have additional requirements (import permits, quarantine, microchipping, etc.). Check with your destination's agriculture or customs authority well in advance. This is separate from Passaredo's rules.

Final Thoughts

Flying with Mochi has gotten easier each time because I learned the rules upfront. Passaredo is generally pet-friendly, but they're strict about advance booking, breed restrictions, and documentation. Do your homework, book early, and get your health certificate. Your pet will be fine, and you'll have one less thing to stress about at the airport.
