First question is whether it is in fact a blue tinted window. Remember 
Mike's pic of a mountain  (Patagonia?) at about 18,000 ft. 
<http://www.moosemystic.net/Gallery/Brrrrr.htm>? Without a warming 
filter, the high altitude UV effect rendered it VERY blue. So how much 
extra blue is there at typical jet altitudes? Of course, the windows may 
filter out a lot of UV for the optic health of the passengers, but how 
much? They certainly don't look like warming filters down on the ground.

On the other hand, they don't look real blue on the ground either, so I 
think we can assume that a lot of the problem is simply UV that the eye 
doesn't see, but that is sensed by the camera, throwing the white 
balance off. So one solution would be the classic one of using a warming 
filter. At over 30,000 ft. unmediated, that would probably be something 
at least an 81C. With the UV diminution of the windows, who knows, 81A or B?

One solution when there are nice white clouds is to ignore the problem 
and just use the highlight dropper in PS on the brightest spot of cloud. 
That's what I did to Mike's pic, before adding a blue sky with clouds, 
that is. :-)

Auto WB on the E-1 is likely to give weird effects, as the ambient light 
sensor may be seeing more or less of the very yellow cabin illumination, 
depending on how it is held for each shot. I'd guess the best bet would 
be fixed WB at the highest color temp the camera will do.
