<prompt> Human: I posted this in rtravel and I hope you guys can help too.So me and my girlfriend traveled home to visit family. And the flight went smooth checked in fine, boarded fine and tickets scanned. But as I was checking in for our return flight it only had my ticket. So I ended up calling the airliner and the agent kept reiterating that she wasnt on the flight so the return ticket was cancelled. I argued she was on the plane and this is completely their fault but she was no help and she couldnt doing anything because its not on their manifold she flew. I didnt take that for an answer so I wouldnt let it go until I talked to a manager.Well I speak with the manager and she tells me that it would be against federal law to put her back on the flight. And the only way we can make things right is to go to the airport and file a federal complaint against them and then and only then will the ticket be reissued. I guess they have a different log than this airliner has and can confirm shes on the flight?How accurate is this information. Was she just trying to get me off the line? And do I have any other way of handling this other than chancing?  <response>: Do you have her boarding pass?
