Can I take this piano keyboard on flight (picture included)?

Based on the dimensions, it's too big to go as a carry on and fit in the overhead bin. Standard carry-on allowance is 22" x 14" x 9" or 56 x 36 x 23 centimeters. The keyboard is 32", so you will need to make sure it is encased properly, checked and I would insure it, or ship it in advance with a reputable forwarding company, such as Fed Ex or UPS rather than entrust the airline with it.
