<prompt> Human: This happened to my girlfriend today. She had a flight booked from kunming airport to Shanghai airport layover in shanghai, and then a flight from Shanghai to the US. After leaving Kunming, the airline flew to an airport that was NOT on her itinerary that airport was called Hefei. The layover in this unexpected stop was so long that she missed her flight from Shanghai home. Now we had to book a same day flight from Shanghai to get her home. The fault is clearly on the airline because they flew to a city that was not on the itinerary. What can we do?Edit: UPDATE- China Eastern Airlines rebooked her flight for free and gave her a hotel to stay overnight IN SHANGHAI for real this time apologizing for the inconvenience in Hefei. Expedia allowed us to cancel the new flight. God is good, folks. Assistant: She should have been put on the next flight out of that airport to the US; did she contact customer service?Human: Not if she booked two separate tickets. Otherwise its the same as simply not showing up to your flight. The airline doesnt owe you anything in that case.Assistant: Its not clear to me whether she was booked two separate tickets, or whether her entire itinerary was on China Eastern. Either way, its moot now. She missed her flight from Shanghai due to her own error and then booked a flight on a different airline on her own.Human: Out of all the screwed by the airline posts on rpersonalfinance Id say near 0 are actually the airline doing anything wrong.Dont get me wrong, the airline industry deserves tons of criticism and derision, but the posts always simply highlight how the OPs made errors on their end and get mad at the airline.Assistant: The gate agent looked at her ticket, and pointed to the door and said your flight is tomorrow.Human: And that was that? Come on, you have to be your own advocate. She knew the flight wasnt tomorrow. She should have been more assertive. It was likely some translation issues.If a US agent walked up to you at LAX and said your flight is tomorrow while youre waiting to board, you know you wouldnt leave it at that. I know you want to protect your GF, but be reasonable here.Assistant: She thought she was in Shanghai when they landed. Which I shake my head at. But the gate agent didnt help to clarify and sent her on her way.  <response>: She thought she was in Shanghai when they landed.Youre really not helping her case.
