I'm having a hard time thinking of any side shot of the cockpit from Chewie's side looking towards Han. It's possible they didn't want to have to deal with showing a bit of the Falcon's exterior in those scenes.

Will be interesting to see if we get that sort of shot in Episode 7 though.

Absolutely SilverWook that is part of the magic of film making. not showing this angle ever in any of the OT Star wars films.

Because it is not filmed in that cockpit.

It's about time Han's Head was there in profile in this day and age
