1. An AirFly Pro wireless transmitter so you (and a buddy) can actually use your Bluetooth earbuds to watch those free in-flight movies.
2. A digital luggage scale if you're tired of playing souvenir musical chairs with your luggage to avoid paying pesky baggage fees. This scale is super accurate, easy to use, and tiny enough to pack with ease.
You can also switch between pound and kilogram measurements.
Promising review: "Works great, a must-have when flying. Very accurate scale. Easy to read with the light on it. It's a must if you have a wife like mine who loves to shop for clothes and fill up her suitcase along with mine, or if you want to stay under that 40 pounds and avoid paying the extra for overweight baggage fees. Easy to use, very accurate, well made, and a nice design. Very pleased. Saved me money." —Amazon Customer
