Diagnosing the problem
Download the ics file associated with the feed to your local machine. You should be able to import the file into Notes just fine.

In this case, a third party application called TripIt was being used to create the icalendar feed. It was found that the URL generated by TripIt was invalid. For additional assistance with this issue please contact the TripIt vendor for additional assistance.
