Be supportive of her choice, if she's asking you to come get her that's a whole nother thing. Keep asking if there's anything you can do. When she gets home you can hold the cost and I told you so for years. You know they do it 😉
But in all seriousness just follow her lead, she got herself into it, you only need to jump into action if she asks for help. If you want to be helpful then volunteer to talk to the airline and make other arrangements. I bet you can find her a flight for less than 1500 if you think about it.
