New Phantom 3 Case for carry-on travel. Fits with props on (tight squeeze). http://silverstatecase.com/product/pelican-phantom-3-case/

According to this chart http://travel-made-simple.com/carry-on-size-chart/ the Silver State Case (22x18x10)  would not meet the carry-on size requirement for most US and International airlines. It is close though, so it would depend on how strictly the airline is enforcing its own standards.

If you're looking for a drone case that fits carry-on requirements, check out CasePro's Quadcopter Cases page: http://www.casesbysource.com/brand/casepro-drone-quadcopter-cases

All cases that are labeled "Carry On" meet carry-on size requirements.  The ones that do not will have to be checked but don't worry!  CasePro's hard cases are heavy-duty enough to protect your drones no matter how roughly they are handled at the airport.  The high-density foam interior, which is designed specifically to hold Phantom 3's, will cradle your drone for snug and durable protection.  You won't even need to remove the propellers!

I work for CasePro, and I would definitely recommend trying the P3 case with our new RecoCell foam: http://www.casesbysource.com/pro ... d-case-cpe-phan3-co

RecoCell foam adds more cushioning and protection. Like memory foam, RecoCell foam shapes itself around your Phantom 3, creating an ultra-snug fit without damaging the drone at all.  You can even customize CasePro's foam interiors to make sure you have a cavity for all your accessories.  Just click the orange "Add Custom Foam" button on the individual case pages and use our online tool to build your personalized foam insert.
