I'm one of the US based coaches for a roller derby team representing Greece at the derby world cup next week. One of my players missed her Aegean flight from ATH to LGW this morning, what's the best way to get her to either Dallas or Austin in the next day or two? She booked with United and her flights from London on are on their metal. Also what type of change fees should there be? She missed the flight by 10 minutes, the plan was still at the gate and they wouldn't let her on.

Thanks
