Hello,
I do not quite understand the excitement about low miles to Keflavik. When I look at the available tickets BOS-KEF paid with miles, it never goes below 62.500 for one-way trip in business seat. Which is exactly what I paid for PRG-AMS-BOS a month ago, for June. So to me, North-America to KEF does not differ from any other European city. Did I get it wrong?
