I have flown with my Tyros and Tyros 2 on more than 50 flights. I use a custom made Hardshell case from a company that is out of business, but you can get similar cases all over the place including ebay. I check it down below and get charged overweight ($20-25), but four times out of five they forget to charge oversize - which is the big cost ($80-100).

Make sure you check in AT LEAST a full hour before the flight if you want your keyboard to arrive on your flight.

I've only once had my keyboard delayed in three years and over fifty - maybe more - flights.
