@Linkat,
I get that, Linkat. Southwest has a target demographic that it serves very well. But don't ever expect a full meal while you fly.
Ironically, Southwest typifies the cost cutting that this thread talks about (although they do it better than most). I think you are old enough to remember when you were served a hot meal on every flight.
Southwest ended that in the 1970s to cost costs and increase their profit, giving customers peanuts (literally peanuts) instead.
I was trying to see if Southwest was amoung the first airlines to cut seat sizes. I couldn't find data from the 1970s to say either way. I do know that Southwest was a pioneer in the practice of packing as many people into a flight as humanly possible to maximize their profits. They made sure that their airplanes were full.
Of course, Southwest is a profit driven corporation. They have changed their policies over the years to make as much profit as possible. Right now that includes free luggage.
