Old thread, but anyway: have tried to book flights using google flights. Found some tickets through United, but each time I hit the select button I´m being redirected to the search site. And searching directly on United.com does not give any flights at all. Originally I searched for four tickets. When searching for five, I come directly to the passenger information side. It seems like four or less won´t give me the ticket, but five or more do. Anyone know why it´s so? Searching for an international multi-city trip, starting in Norway, to USA, and back.
