The times I have traveled with my H9000 and taken it on a plane, I’ve used this case without issue: https://www.skbcases.com/products/4-u-i-series-injection-molded-wireless-mic-fly-rack In order to keep it under 50 lbs, I’ve had to not include any cables, power conditioners, and not much else in the rack. Make sure you weigh it and it abides by your airlines weight guidelines. You have to check it in.
i’m happy to hear the H9000 can survive checked baggage handling. Thanks for the SKB case recommendation. I will try this.
