I am quite upset about a surprise charge I had to pay for my 1 check-in bag ($75.05). This was not listed on my Kayak booking paperwork. This made the return trip sour for me. If this was a valid change, you should have explained it in my quote. If it's not a valid charge, you should give detailed instructions on how to remove the charge from my credit card. I am not going to use or recommend Kayak again, if you cannot resolve this issue.
