As if they've heard your pleas, the folks at Griffin have produced the eXport In-Flight Video Cable. It connects with the in-flight entertainment system that a growing number of airlines have begun using. Once connected, you can watch video and listen to music while charging your iPhone or iPod. The cable is 3 feet long and connects with a 30-pin Dock Connector to 9-pin IFES (9-pin Mini-DIN). Just remember to enable Airplane Mode, lest an Air Marshall wrestle you to the ground.
No more suffering through 6 episodes of 30 Minute Meals! The Griffin eXport In-Flight Video Cable for iPod and iPhone costs $39.95US and makes a great gift for the frequent flyer on your list. Look here for compatible devices.
