Do airplane ticket sites (Expedia, Travelocity, Kayak, etc.) increase prices between successive browsing sessions, as well as manipulate prices so that they are in agreement with each other? [more inside]
Let's say that traveler X would like to fly from city A to city B on American Airlines. The cost to fly from A to B is $500. X notices that a flight from A to C costs $300, and includes a layover in B. What, if any, are the negative consequences to X if he purchases the A to C itinerary, carries his bags on the flight, and leaves the airport after arriving at B, never to complete the B - C leg?

Is Continental airlines going to penalize me for evading their attempt to double my ticket price? [more inside]
How far in advance, or how close to the time, is the most advantageous time to purchase airline tickets in order to get the cheapest fares? For instance, if I were planning to travel in early August, and it's late April now, should I buy my ticket now, or should I wait until closer to the time (and how close is the "sweet spot")? Are there risks of the price going up substantially (more than $100)? This refers to U.S. travel (SEA-ATL in this case), traveling mid-week, with a weekend stay.
