For the Jet-Setter: Orange Circle Studio Pocket Planner
The Orange Circle Studio Planner ($7) is a 60-page paperback agenda that includes sections for notes, goals, and calendar spreads, and it comes in several fun covers. At only 6.5 inches, it's small enough that it won't take up a ton of space in your carry-on and cute enough that you'll love writing in it while you're up in the air.
