She states that it was somewhere they flew.
It obviously was someone she knew. He was a guest at her birthday party. Maybe he did have access to her passport, but she still had to go to an airport, go through airport security and board a flight. Sit for the duration of the flight. Disembark. Walk through the airport. Etc - not exactly easy to do with someone who’s heavily drugged I’d imagine.
It’s not unreasonable to question things that don’t make sense.
I’m well aware that horrific things happen in the world, I’m simply trying to make sense of what she’s claiming to have happened, based on the information she’s made public and it’s patchy at best.
