It'll most likely get checked. If it gets checked, it can get delayed/lost. So, for safety's sake plan to put as many hours as you can between when you arrive, and when you actually need to use the keyboard (to allow them to get it to you) If it does get lost- Raise hell. Tell them it has your insulin or heart medicine or brain pills in it. Airline delivery services have two speeds- "Regular" and "Rush". Rich people, dying people, and hell raisers get bumped to "Rush".)
The Airline's website will have a page for luggage dimensions/prices.
