We flew with Travel City Direct last January and had seat back TVs. That was when they still used European Aviation planes - now I think they use Air Atlanta, among others, I'm not 100% sure. I'd have thought they'd have the seat back TVs though.
We flew TCD last August. It was an Air Atlanta plane and there were no seat back TVs The screens were at the front and quite difficult to see. The sound through the headphones was good - not crackly.
we are flying with TCD again this year but on one of their own planes so not sure if they have seat back tv or not.
We flew with TCD on Air Atlanta last April in Sunshine First and there were no personal TVs, just a screen at the front of the plane which was not easy to see because of the amount of light in the cabin.
