I have just downloaded TripCase for an upcoming trip. Can someone explain does it take the flight details from your booking reservation, or the flight number details?

I sent a confirmation for an Icelandic Air flight. About 10 days after booking I received an email advising that my flight details had changed. I was originally booked on FI 416 departing at 1030, and this was changed to FI 418 departing at 1030. However TripCase has imported my details as being on FI416 departing at 0730. I have logged onto the Icelandic air website and it is still showing me as being on FI418 @10.30.

Any thoughts appreciated.
