Airlines have strict guidelines to ensure the safety of both passengers and pets, so bringing pets on flights is more complicated than just packing them in a backpack. A pet carrier that has been approved by the airline can help with that. In addition to meeting cabin size restrictions, these carriers are made to offer adequate ventilation and ensure your pet's safety and comfort during the trip.

📏 What Determines an Airline-Approved Pet Carrier?

Taking your pet on a flight? ✈️ You can make the trip easy and stress-free for both of you with a little preparation and assistance from Trip.com!
✍Make Your Reservations Early
Use Trip.com's flight booking filters to reserve your space in advance, as most airlines have a cap on the number of pets that can travel in the cabin. When searching, opt for "pet-friendly" alternatives.
📏 Be Aware of the Carrier Policies
Every airline has its own set of guidelines. Make sure your soft-sided carrier satisfies the requirements (typically under 18") by using Trip.com to check the most recent in-cabin pet carrier size limits.
🍖 Forego the Large Meal Before the Flight
Motion sickness may result from feeding your pet soon before takeoff. Food should be withheld 4–6 hours before takeoff, according to veterinarians.
😘 Maintain Your Calm—It Helps!
Your pet senses your feelings. Your travel companion is more likely to remain composed if you are at ease.

What dimensions of pet carriers are permitted in the aircraft cabin?
The majority of airlines demand soft-sided carriers, which are usually around 18" x 11" x 11" and can fit beneath the seat in front of you. Prior to taking a flight, always check Trip.com for the specific criteria of your airline.
Do airlines approve of hard-shell pet carriers?
Soft-sided carriers are more frequently approved for cabin travel, but some airlines permit tiny hard-sided carriers in cargo or under certain circumstances. They fit beneath chairs more easily and are more flexible.
Does every airline allow me to bring my pet?
No. Pets are not always permitted in airplanes. To see airlines that allow pets, such as Delta, United, Air Canada, and Lufthansa, use Trip.com filters. Only pets are allowed as cargo on some airlines, such as Singapore Airlines.
