Well i was flying through a lot of clouds today, in a EMB-145, the plane was
mostly flying thru clouds, even then i did not note any ice on the windows. the
humidity inside the cabin is also pretty low to allow condensation on the
windows

It is highly unlikely ice will form in this season. I have seen ice crystals
only once on an Air india flight ht went thru frankfurt B747

That too was like single crystal formation

to check out this page, where ice crystals were formed on a B777 at 37K height.

could now bring to your attention on some photography tips, which you might like
to learn, before you board the flight. Check this fine page on "How to take a
photography out of a plane window". It covers various grounds which friends
failed to provide.
