Umm, I may have had a little too much Brennevin, but ....
I'm going to be travelling to America next year to see the eclipse and, being in Aberdeen UK, the obvious choice is Icelandair as they fly to America from Aberdeen airport.
And even continuing through the whole of the original post, I cannot find any reference to the AB (Northern Lights).
Out of interest, at what altitude do the AB 'happen'? (Sorry if I've not phrased the question correctly ... but would you not be likely to be 'too high' for them at cruising altitude, even assuming they stay still.)
Genuine interest, no scientific knowledge per se, user-friendly comments welcomed! ;-)
