Here's an interesting tidbit I just learned. TPG is the parent company of Indigo, the parent company of Spirit Airlines. Odd that NWA would partner with the parent company if their biggest rival in DTW. Even more odd that this happens a week after Spirit announces the closure of its DTW base and the desire to refocus its strength in the Latin market. Preemptive move to satisfy antitrust concerns?

Things that make you go hmmmm.
