For years and years, airlines had lost money. I'm not talking about a few hundred or even a few million dollars, but many millions of dollars. This was mostly due to fuel prices and costs associated with wages and maintenance. Then the idea of charging for luggage and the other extras became a reality for many of today's airlines, except Southwest.
As for meals, flights over four hours on United still get a short meal, except for anyone sitting in one of the upper classes of service. The pilots eat pretty good when food is onboard. I was a bit paranoid when it came to eating. I never ate at the same time of my F/O. I was always concerned that some of the food would be tainted and we would both become ill, so I either ate a different entre or at a different time from my F/O. Just to be on the safe side.
I can still remember when people dressed a bit differently than they do today. Men either wore a suit or dressed in business casual. The women would wear a suit or business casual as well. Very few women would wear a dress when flying.
