So, was viewing this here.... (the woman and little girl are seated at approx 06.55).
And was surprised to see the facing seating arrangements, as I never thought this was the case (outside early heavy jet first class configurations where anything seemed possible), so the early BEA Trident seating configuration had some seats facing each other?
This was rather a surprise to me, thought it might also be of interest to some (the footage is also historically interesting).
I have seen this also on some other Trident footage (viewed after this) that confirms it seemed standard around the time, just one pair towards the front of the a/c.
Was this carried forward later with Trident services or did they take these out?
