Yes, like WRX, I take mine everywhere, however I've never been international. There are some countries that charge a tax for bringing drones in, but I think you'll be OK with Hong Kong. Like WRX, I keep my drone with me all the time, I never check it. I recommend a backpack for easy carrying when you arrive. Batteries MUST be carried on, you cannot check them, hence I always keep everything together in a backpack that give no clue what's inside. Don't buy one with a drone logo on it. As you get on the plane, if the overheads look like they're getting full, grab the first space you see open, because you MUST find an overhead. Even if you get a backpack that's 20X14X9", that won't fit under a seat many times, but it's a good idea to get the smallest backpack possible for flexibility of storage in overhead. Make sure you know the regulations for your airline because may employee's "Think" they know the rules, but don't. Be prepared because there is a lot of uninformed airline workers that aren't.

I have several backpack of various qualities.
The Chinese Cheapy (as I call it) is the smallest and lightest of all the ones I have. It actually has more room than the DJI hard backpack, and it's less than $50. I've had one of these for about a year. The fabric isn't the best, but it works, especially if you don't plan to travel much. I just took my CC backpack across the country, it continues to hold up and have plenty of room. It provide pretty good value at a minimum cost. My Think Tank backpack is what I use the most around home, it's more durable with even more room.
