There are a number of problems with that so-called article, but I see no attempt to make it controversial of cliff-hangy.
First, it's not an "article" (any more than this post is). It's a social media post pretending to be journalism, nothing more. It's basically, "hey I went to Europe and flew around a bit. It was OK." Where's the new value in that?
BREAKING NEWS: OCEAN STILL WET, try this one crazy trick! Now THAT'S journalism.
The rules are the rules, and anyone who ignores them gets what they deserve.
Calling the airlines "stingy" (which the article never did) seems pretty unfair to me. The airlines are simply giving their customers exactly what they demand - cheap, cheap, cheap tickets, to the exclusion of any other consideration. If your flight costs no more than a fancy cup of coffee, don't be surprised if there's no in-flight shower or caviar bar. People demand tickets that cost less than a trip to Mickey D's so that's what they're selling. If you don't like it, stop shopping and paying for flights to the exclusion of any other consideration.
Personally, I try to avoid the cheapest possible anything, that includes airplane rides. Sometimes the cheap-o option is the only flight serving a route I want, and in that case I'll suffer the low cost airline experience for a short bit, but I'll typically pay for a checked bag and maybe other amenities.
And if the "stingy" label applies here, it's on the customers, ain't it?
