Travel meta-search
Much as BookFinder searches many book sites to obtain useful price comparisons, Mobissimo (and a few others mentioned in a recent Associated Press article) search many travel sites to obtain useful price comparisons. I tried it and was pretty impressed, especially for international travel (which has a completely chaotic and non-transparent price structure at the moment, so that searching multiple travel sites can really make a big difference). For example, a trip to Germany in January which I had just purchased for about $800 roundtrip turned up on Mobissimo for about $650. Mobissimo and other travel meta-searches also apparently search JetBlue and Southwest and perhaps other discount airlines that are usually not searched by other travel sites.
I wonder if they're scraping with or without permission, or perhaps with some mixture of the two. Why would JetBlue, for example, want Mobissimo to scrape its site, but not want Expedia, Travelocity, Orbitz, etc., to do the same?
