My thoughts:
The Airline Industry in general is in for years of unrest yet. There's too much debt, too little margin, too much competition to raise prices, and the Hub and Spoke model is eventually going to implode, OR be a serious drag on the industry for years. I say that because no matter what the "experts" claim, there is NO magic software or hardware that is going to let 80 airplanes land and takeoff from a single runway in an hour. Not unless Boeing invents a VTOL airliner. And even if you could land/depart 80 per hour per runway, there aren't taxiways and gates to handle them. I say this after having gone back to work yesterday evening and finding 2 hr delays and/or ground stops to half the major airports east of the Mississippi. JFK, LGA, EWR, TEB, BWI, IAD, ATL, PHL, ORD, plus IAH here in Texas are just the ones I remember from yesterday. Customers just love arriving 2 hrs early for security lines, and then sitting an additional 2 hrs past departure time for WX and congestion delays. It's cheaper, easier, and more convenient nowadays to drive 6 hours. That's a fact.
From an ATC standpoint, RJs are going to further choke the major airports. Instead of one 757, the airlines are buying three RJs. Unless those RJs are moved from the Hubs and placed on more point-to-point routes between minor or mid-size cities, the larger airports are just going to become a huge traffic jam. I believe the RJs CAN be used effectively; but they're going to have to fly LNK direct OKC for example, not LNK-STL-OKC. Or LNK-ORD-OKC. What I don't believe is that the bean-counters will ever admit that Hubs are a bad idea operationally. They look great on paper, but suck real-world. Did anyone notice that ORD's traffic actually went UP after AAL and UAL agreed to reduce some flights?????
$100k per year a good salary? Yes, if you don't live on the coasts, or another higher cost area. And if you aren't divorced and paying a quarter of it to your ex, and if your current spouse works, or will drive a 5 yr old car and shop with coupons, and if you have good health insurance and no serious medical issues, etc. etc. You can be very well off on that single in Texas. You can be shopping for Palm Harbor Homes if you're divorced in California.
