And it's the consumer that drove this, people who said hey, I'm willing to take the risk to pay less.
People are willing to take the RESPONSIBILITY to pay less (be on time, or miss out. Self check in, etc etc).
I fly quite regularly, at no point did I see it clearly stated "These cheaper tickets are less likely to 'work' when you want them to"
Yep, we wanted to pay less.
We now have 0 in-terminal baggage handlers, it's all self scan, and self load.
We no longer get free food on flights.
We no longer have 'entertainment' in the terminals (all the 'free kids lounges' or arcade machines are gone to make room for more retail, who pay rent).
Once on the flight, I'm fairly sure they've 'added another row' of seats these days. (I'm single cm's shy of 6ft, and my legs LITERALLY don't fit between a QANTAS economy chair gap, last flight I had to stand for most of it, and sit in business class for landing; I'm not a 'big guy', just made of majority legs. )
All the 'in seat' movies and drop down theater screens are gone, they now rely on you using your own phone\tablet.
Hot towels and free mints for takeoff and landing seem to be gone.
I'm sure I could come up with more....
After all those sacrifices, I'd expect to pay less.
Cutting food, and cutting 100% of your in terminal baggage staff must have been a GREAT saving (to pass on, hint hint).
At no point would 'less reliability' have been what the consumer 'drove' the business toward.
