First of all, I filtered my search on Kayak and I DID mention that I needed flights with bag. So rated were presented to me and I picked one. I purchased the ticket, and I did not know that the bag was NOT included (although I did search rates with bag) so one big lie from Kayak. Please fix your search algorithm.
