Will My Pet Carrier Fit Under an Airline Seat? Guide
Will my pet carrier fit under an airline seat?
Most airlines allow small pets to travel in-cabin as long as the carrier fits fully under the seat in front of you. While exact sizes vary, common under-seat maximums range around 17–18 inches (L) x 11–12 inches (W) x 8–11 inches (H). Soft-sided carriers are often preferred because they have a bit of “give,” helping them slide under the seat while keeping your pet cozy and secure.
How to know if your carrier will fit
- Check your airline’s pet policy: Each airline lists size and weight limits for in-cabin pet carriers. Look specifically for “under-seat dimensions,” which can differ by aircraft and seat (window, middle, aisle).
- Measure your carrier: Measure length, width, and height when fully zipped and packed as you would for travel. For soft-sided carriers, make sure they can compress slightly in height without collapsing on your pet.
- Measure your dog: Your dog should be able to stand up, turn around, and lie down comfortably. Compare your dog’s back length and shoulder height to the carrier’s interior.
- Choose soft, structured comfort: A quality soft-sided carrier with breathable mesh, secure zippers, and supportive base helps meet airline rules while keeping your pet calm.
- Plan your seat: Some airlines have smaller under-seat spaces in certain rows. When possible, select seats with more consistent under-seat clearance and confirm aircraft type.
Pro tips for a smoother flight
- Acclimate early: Let your dog nap in the carrier at home so it feels like a safe den.
- Pack light and organized: Keep essentials—leash, collapsible bowl, treats, and potty pads—within reach.
- Arrive early: Gate agents may visually confirm carrier size and pet comfort.
