Southwest Airlines is making it easy for iOS device users to iMessage in the friendly skies. The U.S.-based carrier announced today that it is offering access to Apple’s messaging service for $2 per day.

Any iOS device with iOS 5 or later with iMessage preinstalled can take advantage of the option.

For $8 a day, users can purchase full Internet access, short of streaming video and VoIP sites.

And even if you’re not willing to pay anything extra, the airline has teamed up with Dish to offer, for free, 13 live television channels and up to 75 episodes of popular TV series. Along with iOS devices, Mac and Windows users can log on and watch the free entertainment.

Unfortunately, not all Southwest planes are offering the Wi-Fi access. Fliers can surf on over to Southwest’s site to see if their specific flight is Wi-Fi ready.

The inexpensive access to just iMessage is a very nice option from the airline, especially during the very busy holiday travel season. Like other major U.S. airlines, Southwest now allows fliers to keep their electronic devices on from gate to gate. During taxi, takeoff, and landing, the devices must be in airplane mode.
