Interesting article but it is definitely travel agent oriented. I don't know of too many agents who are going to find out if there is a high school band trip booked at a hotel during your stay or take the time to find out if there is nearby construction. I'm also not sure if a travel agent is going to get you a better deal on a coach seat than you can through the airline's website unless you are flexible on your days and airports.
The point about "bundled" is true. It's like the cruise line "From $299" pricing. It is for the lowest category and the bundle is for the cheapest hotel, sub compact car, and three connection-red eye flights.
