A ticket purchased for a particular flight is a contract for service, just read the fine print when you book a flight. That applies to the provider as well as the consumer. Knowingly overbooking a flight or using a paid seat to transport an employee is unethical and should be considered a breach of that contract. If the government has to actually pass a bill to force ethics into the airline industry, the industry has bigger problems. The DOT just removed the regulation requiring carriers to list their baggage fee policy so the consumer knows the actual cost of a flight before they commit to purchase. What makes anyone think they will enforce this legislation if passed, especially in this hyper pro-business administration? I agree the practice should be stopped, but it should be because the company deems it unethical. I realize that is wishful thinking, but I am eternally optimistic.
