We've seen in other markets that going from four to three results in increases in costs for consumers, while keeping investment levels flat: https://www.economist.com/news/business/21699143-country-mer...
I knew nothing about this. My irritation towards the airline industry is entirely based on poor quality / service, which seems (to me) to be the result of my having no meaningful options as a consumer.
Try starting an airline with free checked baggage, free meal and more legroom. If your ticket price reflects the added cost you'd be bankrupt in a few months.
Would it be so terrible if the legacy airlines were thinned, and more Southwest/JetBlue/Virgin America-type newcomers showed up? As it is American, United, and Delta are the largest three airlines in the world because they all had fairly sizable mergers.
This makes me wonder if those advantages of scale aren't greater than I thought, and maybe the merger would be beneficial.
But as a great admirer of what T-Mobile has done, and a since-voicestream customer, I'd hate to lose their scrappy underdog nature.
