Maybe. At least for short flights I can agree with that.
But I can tell you the tickets I just purchased I do not consider cheap. Especially without even a meal included.
That said, I guess maybe the answer is just don't fly so as not to be subjected to the torture the airlines put you through. If you even have that option...
You make a very good point. It may not be this way, but it "feels" like they take away frills, give you a discounted price, then the price creeps back up to where it had been before the benefit was taken away.
I remember when they started reducing the ice cream container size from a quart down to 24oz. The price had been, say, $4.00, and went down to $3.50. Within two months, price was back up to $4.00. So now we get 3 cups for the price of 4. I hate feeling like I'm being manipulated.
