I've noted that travelers seem to vary as much in what they do during a flight as with everything else in life. Some are glued to videos on their backseat monitors or ipads. Others love to read their kindles or -- in a throwback to the good old days -- real printed books and magazines. Some seem to need certain headphones or articles of clothing, etc.
I'm kind of curious about what the TravelGumbo community can't live without on a plane flight.
For me, it's recorded books. Formerly filling my iPod but now on my smart phone, I love to sit back and be entertained with the spoken word. And I like an ExOfficio shirt with 2 pockets (one for passport, tickets etc and one for my smartphone).
What about you? What indulgence makes a flight that much better?
