It should come as no surprise that the healthiest thing to drink on a plane is water, which also happens to be the healthiest thing to drink on land.

Water is preferable to keep yourself from getting completely dried out. Also, unlike alcohol, drinking too much water has never been the cause of inflight fights or nastiness.
