Do not assume that a no-frills carrier is going to be the cheapest, particularly for late booking. One thing to look at is the airline alliance Web sites,
One should aim for state of the art travel, which is about getting the best value for travel, not the best price,
Target a flight that is likely to be full or overbooked. Airlines overbook because people do not turn up. Sometimes their projections are wrong and they will upgrade one or two people, (this is called cabin roll).
