One hypothesis: someone who is looking for stock prices would search Google Finance or search for "LUV"; someone who is looking for ticket prices will search "YYZ to SFO", and someone who is looking for wikipedia will search "southwest airlines site:en.wikipedia.org".
I suspect that's exactly what this experiment seeks to test. Is this giant banner result more relevant for users searching "southwest airlines" than the knowledge graph box that contains Wikipedia, Stock Prices, and a Flight Status prompt?
If so, then we'll start to see these "banner ads" become more common. If not, they delete some code and everything goes back to the way it was.
Rather than theory-crafting, Google is measuring their users' behaviour. As I feel they should be.
