"Most people aren’t actually paying $11 to fly — they may pay for seat assignments, bags, beer, lottery cards, etc."

"An airplane is marginal cost with wings." Alfred Kahn, 1977.
An airline or other business can run growth experiments to discover the optimal mix of loss leader combined with cross selling and upselling. This will attract competitors willing to take a lesser return, which can make industry returns = opportunity cost of capital. Got a moat?
Airlines selling things like credit cards is a cross sell. I've yet to see lottery cards sold, but that too. More leg room is upsell. Every variation in the ordering process can be tested and retested in growth experiments. If a business today can't do this testing, it is toast.
Munger and Buffett have changed their minds about investing in airlines since I wrote this. google.com/amp/s/25iq.com…

The more current BRK view is that the airline industry has some pricing power. The dominance of airlines at some hubs is one change. finance.yahoo.com/news/charlie-m…
