AIR travel, as an experience, sure leaves a lot to be desired.

Smaller seats, higher baggage fees and ticket prices (despite lower fuel costs) are just a few of the myriad complaints.

On the bright side, however, airlines are making more money, and after years of outdated in-flight entertainment, investments in onboard technology may entertain passengers enough to make the miles go by more quickly.

Most United States carriers have, in recent months, announced updates and improvements to their domestic in-flight tech that, in some cases, even provide free entertainment to the poor souls back in coach.

These new services let you use your own mobile devices, like tablets, laptops and phones, to either stream free content like TV, music or games, or to rent movies and TV without having to pay for a Wi-Fi plan.
