> I think Airplanes are going to be pretty profitable.
Anything at sea, too. Going on a cruise? The cruise ship can offer you Wifi backed by Starlink for another few bucks. Or even your cell provider could get you hooked right up to Starlink for some phones.Container ships, military vessels, even fishing expeditions could enjoy an internet connection and cell service.
Worldwide there's roughly 30 million recreational boats, whereas for commercial aircraft carrying people (not cargo) is more like 30k, so different orders if magnitude. It's highly likely boating would be a more profitable industry to satisfy demand for than airlines in the long term. That is unless they're charging exorbitantly more for airline contracts than personal boat use, which is totally possible.
I think SpaceX is an incredible company but at this valuation I’d expect it to have something as pervasive as the iPhone or Nvidia chips. It seems to have only small niches.
SpaceX has the lion's share of the world's launch market, if you include Starlink.
Frequent flyers choose their airlines for a lot of reasons - which airline has the most direct flights from their city, who has the best frequent flyer program, etc. The latency of the Internet is seldom a factor or the difference between 10Mbps and 50Mbps.
Non frequent flyers just buy the cheapest flights. The major three airlines make money off of business travelers, business and first class flights and credit cards.
