Hilary Scott asked me to post this for her, since she is STILL traveling.
She experienced delays in Chicago due to a thunderstorm. Circled until the plane got low on fuel, then they were diverted to Peoria for refueling. Although late, she made her connection to Alitalia for the flight to Rome. Halfway to Rome the plane was diverted back to New York because the radar stopped working.
Quite late last night they found a hotel for everyone near the airport in New York, and she hopes to be flying out today at 3:00 pm Eastern for a very early morning arrival in Rome.
