Iceland Express turned out to be just fine for us. Pretty much on time, despite weather issues in London, comfortable, and it got us where we wanted to go. It's a budget airline, so everything is for sale; or you can bring your own, as we did (cleaning out the cupboards...sausage from Colmar, pistachios from Gaziantep, cheese from Amsterdam, gingerbread cookies from Aachen, etc). Iceland Express jets you first to Rekjavik, Iceland, in three or so hours, and then, after an hour or less in Rekjavik (enough to visit the duty-free stores and sample Icelandic vodka), five hours to Boston, where we are presently. We give Iceland Express 4 stars; 5 when you factor in the price. Plus our passports now sport Iceland stamps.
First sight of Iceland; had I been sitting on
the port side, I would have seen Surtsey;
but not Iceland
Mostly pretty barren, with lots of volcanic
A mini caldera
Temporarily well-behaved volcano
