Frequently Asked Questions

Is Sleepypod Atom suitable for airline travel?
Most airlines accept Sleepypod Atom for in-cabin pet travel. Since each airline and airplane is a little different, Sleepypod always recommends contacting the airline prior to travel, just to make sure all pet restrictions and requirements are met. 


Can Sleepypod Atom be used in the front seat?
Sleepypod recommends buckling your pet into the rear seat, just like you would a child under 95 pounds, to better ensure safety. 


Can more than one pet use the carrier at a time?
Pets can share the carrier at home, but Sleepypod cannot recommend more than one pet per carrier during travel due to the number of variables involved. Please note that it might reduce safety. 


When do I use the safety tether?
Sleepypod recommends using the safety tether only during public transit to keep your pet from escaping the carrier. The safety tether feature should not be used for car travel. Watch the Pet Travel Experts “How to Use a Safety Tether with a Pet Carrier” video at


Is it necessary to replace your pet’s safety restraint after a car accident?
Just like a human seatbelt in a car accident, the material will stretch. Just a little bit of extra slack can reduce its effectiveness. Watch this Pet Travel Experts video at


Will Sleepypod replace my pet’s safety restraint after a car accident?
Yes, view the details of Sleepypod’s Crash Replacement Program at


Does the carrier have to be zipped closed all the way?
During car travel your pet should be fully enclosed to ensure safety.
