Deletion of FlipKey

Comment: I can find passing mentions of people advertising on Flipkey among other sites, and on TripAdviser taking a majority share in 2008, but nothing to establish  or  notability in its own right. It is already covered in sufficient depth on the :TripAdvisor page
Stance: delete
