We booked our flight on Icelandair in September 2017, about 9 months before our June-July 2018 trip. We planned to arrive a little before midnight and spend two nights in Iceland’s capital city of Reykjavik. But, as we’ve experienced before, the risk of booking a flight so far in advance is that the airlines may shift their schedules. A few months before our trip, we learned that our flight had shifted to being a red-eye, getting us in the following morning at 6:30am local time. We contacted our Airbnb hosts, who had no problem with the delayed check-in.
