I just see this as wasting people's time and money. In order to do this, you will need to:

1. Call and make a reservation, costing the airline phone time and the reservationist's time or wait in line at the airport/CTO, again wasting an agent's time. Meanwhile, people who are actual customers will have to wait longer to speak to someone on the phone or get to the front of the line in person.

2. The airline will ticket you and charge your credit card money. The transaction is relatively insignificant on the credit card processing system. But, the airline is going to mail you a ticket and/or receipt if you buy it over the phone, or give you a ticket and receipt in person. This is a waste of paper. Again, maybe not a significant one, but a waste, nonetheless.

3. You'll have to go through security. Since you won't have any luggage, you might look suspicious and get a more detailed screening. This will delay the screening of real passengers, some of whom may have a plane to catch in a hurry. This delay may be a few seconds or a few minutes, depending on how many people you occupy and for how long.

4. After picking someone up/dropping someone off, you're then going to either call the airline or show up in person. Again, you'll be wasting more people's time and paper.

Phone calls to companies can cost anywhere from a few dollars per call to $20-25 per call. Mailing stuff costs around $0.50-$1. Agent's time in person is difficult to quantify and, like paper, is a relatively insiginficant cost.

Though adding up all of these costs still comes up with a relatively low total cost, you're still wasting time and money.

Perhaps if you can manage to purchase a cheap ticket, let's say $20, and not request a refund, then I'll be satisfied.
