What is In-Cabin Pet Travel?
In-cabin pet travel means your pet accompanies you in the passenger cabin of the aircraft, traveling in an airline-approved soft or hard-sided carrier that fits completely under the seat in front of you.
Key Characteristics:
- Pet stays in their carrier for the entire flight
- Carrier counts as your personal item (not carry-on luggage)
- You remain with your pet throughout the journey
- Available for small dogs and cats meeting size/weight limits
- Not allowed on all routes or airlines
Who Can Travel In-Cabin:
✓ Small dogs typically under 15-20 lbs (including carrier) ✓ Small cats typically under 15-20 lbs (including carrier) ✓ Some airlines allow rabbits, birds, or other small pets (check policies) ✓ Service animals have different rules and accommodations
Size and Weight Requirements
The most critical factor for in-cabin eligibility is whether your pet and carrier meet airline size/weight limits.
Standard Weight Limits:
Most US Airlines:
- Maximum 20 lbs (pet + carrier combined)
- Some airlines limit to 15-18 lbs
- Check your specific airline's current policy
International Airlines:
- Limits vary widely: 8-17 lbs common for European carriers
- Some airlines don't offer in-cabin pet travel at all
Carrier Dimension Requirements:
Carriers must fit completely under the seat, which varies by aircraft:
Common Maximum Dimensions:
- 18" L × 11" W × 11" H (typical for economy seats)
- 17" L × 10" W × 9.5" H (smaller aircraft or bulkhead seats)
- Soft-sided carriers may have some flexibility
- Must fit without forcing or cramming
Important: Dimensions vary by:
- Aircraft type (larger planes = more space)
- Seat class (first class typically has more room)
- Specific seat location (bulkhead seats often have less space)
How to Know If Your Pet Qualifies:
- Weigh your pet accurately
- Add carrier weight (typically 2-5 lbs)
- Compare to airline limit
- Measure carrier dimensions and verify against airline specs
- Test fit: Can your pet stand, turn, and lie down in the carrier?

- Receive confirmation number
Step 4: Arrive Early
- Check in at ticket counter (not kiosk)

Booking Tips:

Tips for Security:
- Use a harness with leash for added security
