Ours too was uneventful. But CPH to EWK (Newark) is less than 9 hours. Did you have a layover or direct flight?
If I was traveling from the west coast (California) I think I'd do it in two days. Ugh.
See you in Laramie :-)
It was ~3 hours from CPH to Reykjavik, ~2 hour layover, and then ~6 hours (direct) from Reykjavik to Denver. Not terrible, just boring! :-P
