Less than a week after withdrawing its bid for wireless broadband provider Clearwire, the No. 2 satcaster is taking to the skies for a new partnership. Dish Network and Southwest Airlines unveiled a promotional deal today in which the carrier will offer live TV via satellite, paid for by Dish. In return, travelers will see air a 30-second Dish spot when they start watching, and the satellite provider’s ads will show up in confirmation emails and at airports. The promotion, which runs through September, will give passengers access to 14 live channels and 75 on-demand shows on their phones or tablets during about 60% of flights on Southwest, which carries more than 100 million passengers annually.
