I didn't notice any significant temp fluctuation, but I was on the starboard side going south, so we had the sun shining right on us with the shade closed (and the shade sure felt hot). But that could have contributed to keeping my area relatively stable if the temp was falling in other parts of the plane.

Speaking of that, those Embraer shades that pull up rather than down were kinda interesting. Unfortunately the sun was shining right in my eye and there was heavy cloud-cover, so I didn't get to use the nice sized window much.

I've got to say, I'm very much a "buy American" guy and I am more likely to fly airlines that fly Boeing aircraft for that reason, but B6's set-up on the A320 and E190 is really nice...better than anything I've seen from any Boeing configurations. I really like the bins in the E190...nice plane.

Now if B6 would just get a gate at DCA. ^
