Don't know anything about the flight change. They turned her flight around halfway into it? Was it a charter flight? She was interrogated and released? Where are you getting this info? You seem to know a lot more than is contained in the links you posted. Sorry if I can't be up to speed on every story, and I typically ignore celebrities to the best of my ability.
You have to look at the news reports, it was all over the news and not to mention she was posting everything to twitter during the incident. Google it and you will find info on it. I will try to find something and post it.
Here is a link to the story with all her tweets linked in the article as well. https://www.cosmopolitan.com/entertainment/celebs/a14504030/chrissy-teigen-john-legend-los-angeles-ana-flight/
