We're doing to WOW Air deal this June going from CVG (Cincinnati) to CPH for some business and fun in Copenhagen. We opted for a delayed layover in Reykjavik, 7 hours to be exact. I'm trying to discern when we'll have to go through customs and immigration on our return flight - at KEF (Iceland), or when we get back to the states in Cincinnati. As a reminder, we are leaving the airport for quick trip to the lagoon for a few hours before our return flight home.
Thanks in advance,
Ashley
