Missing, extremely new, or very obvious to obtain.

Reference to the 2003 short story collection "Changing Planes" by Ursula K. Le Guin. The general concept of the book is based on a pun: that the low-level discomfort of forced occupation of an airport while changing planes can, in fact, cause one to change from one "plane" of reality to another. Because of the different flow of time in other planes, one can spend a week visiting another plane and return in time to make a connecting flight. - Credit: Necrosyrtes
