The FlightAware plot stops about 2 minutes earlier, so it doesn't add much to what we already knew from the FR24 data, except that it does usefully include groundspeed.
Looking at the GS inbound/outbound in the hold, there appears to be a slight headwind (northerly) component of about 15-20 kts (at FL210).
GS in the cruise was about 375 kts, again suggesting a similar headwind at FL300, which can't have helped under the circumstances.
