Etgar Keret said this quote

Flights are expansive moments when the phone doesn't ring and the Internet doesn't work. The maxim that flying time is wasted time liberates me from my anxieties and guilt feelings, and it strips me of all ambitions, leaving room for a different sort of existence. A happy, idiotic existence, the kind that doesn't try to make the most of time but is satisfied with merely finding the most enjoyable way to spend it.
