The flights were supposed to be with SAS only, but I was mailed by United, requiring documentations for international travel. Before contacting the customer service, I thought this may have been spam/scam... However it was impossible to do an online check in from all SAS, United and Kayak websites. I was therefore forced to check in at the airport with United (again, I wouldn't have known if I had not contacted CS). What really managed to piss me off is that at the time of the check in, not only United was not able to check me in with SAS, but the first flight was also arriving in Chicago at the terminal 1,with the second departing from terminal 5! These terminals are at the opposite poles of the airport (need a shuttle, because it's impossible to walk) and I had to check in and pass through the security again, with a 1:30 hour layover on a transatlantic flight!! Furthermore, Kayak HID THESE DETAILS UNTIL I FOUND OUT AT THE CHECK IN AT THE TIME OF DEPARTURE. I was lucky enough to catch that flight, but only because there was no line at the security. In my case I wasn't traveling for tourism, but I was on my way back to my home country, on the grace period of my US visa. I think it's easy to figure out how many issues losing that flight could have caused to me... I also think this is a deeply irregular way of selling tickets and that kayak should have accounted liable for the issues I may have ran into.
