I was just browsing around some older posts and came across this article in the New York times. Wow, now you can list your booking and get rid of a discarded journey. True, you will still walk away with out-of-pocket losses (the article suggests 45% + handling of 15%), but that should allow you to recover 40% or more of a booking that would have otherwise incurred a 100% loss.
Still in its infancy, there are detractors and negative initial experiences. But these are nascent and will probably take off quickly once travellers get the hang of how this can work to their advantage. Imagine staying in the Marriot for $300 when it normally costs $500. Yeah, some unlucky bloke cancelled and lost $200+, but then it was his/her decision right? In consolation it was not a total loss for the seller.
As with any hotel booking innovation, it is the vendors (ie hotels) who might resist this the most. But this article suggests that there is a business case to helping otherwise stranded travellers who cannot get any refunds.
Definitely one of the travel trends to watch.
