This may come off looking like an attack, but I don't mean it to be. But, if you haven't flown in four years, how can you make statements like the following:
Maybe I'm reading to much into your post. But, it sounds like you're letting media reports influence your opinion of companies that you don't use.
Remember, the loudest voices are rarely represent the majority. I think it's worth noting that US airlines transport over 2.4 million passengers every day. You don't hear about all the people who get to their destinations safely and on-time because it's so common. The media only reports on the tiny number of "bad" experiences.
In terms of pricing, it is true that it does cost more on average that it 10 years ago. But, when you adjust for inflation, the cost to travel by air is lower than it was when comparing back to 1990.
In this chart, the bottom line is the average price paid for the "all-in" rate that includes fees like baggage. The top line is the inflation-adjusted price using 2018 as the basis.

Don't get me wrong. I'm not a fan of the airlines. But, as other people have noted, there's so much more driving what's happening in the transportation sector than mergers.
