The rap on Southwest.

Through good times and bad, Southwest Airlines stays on brand as a no-frills, low-cost, wacky-humored carrier.

Here's a video of one of their flight attendants on a flight to Oklahoma City this month doing his safety announcement as a hip hop rap—with passengers stomping and clapping along.

Note: In a tight economy this kind of customer service (keeping the passengers musically entertained while imparting necessary information) doesn't cost the company a thing!
