If you’re planning to go on a long plane ride but have a painfully short attention span, have I got a book for you. ‘‘747 Things to Do on a Plane’’ by Justin Cord Hayes gives you, yes, 747 things to do to make a long flight feel less tedious. Hayes’s ideas range from no-brainers (read the newspaper) to morbid (write your own obituary) to bizarre (draw tattoos on your arms). His section on making lists is thought-provoking and a possibly eye-opening use of time (list the top 10 happiest moments of your life or the top 10 vacations you’ve ever taken). He gets desperately snarky in the section on pranks. Sneaking into first class (then what?) is one thing, but belching the alphabet and kicking the back of someone’s seat? Not that anyone who knows how to spell air marshal would actually act like such a jerk on a crowded plane, but still. The book is better than a magazine, makes a great gag gift, the word puzzles included are clever, and you won’t mind if you leave it behind when you finally arrive at your destination.
