Perhaps this is conspiracy, but what is the meaning of seat recline measurement in unit of length inches? How is it measured? Does industry standard exist? What is the interpretation in relation to reported recline angle? I try using google search engine but only results related to ethics of reclining a seat or definition of seat pitch.
To be clear, this question is not about seat pitch, seat width, or the person sitting behind me.
I understand that airline marketing team try to obscure this because of ethics or consumer realizing that reported recline actually poor in reality, so please make comment on comparability between airlines with seat recline length or angle (in context of measurement methodology; e.g., if both Airline A and B report 8" recline then is recline equal in reality, or if both report 120° degrees is recline equal in reality)?
For example, Singapore Airline SQ reporting premium economy recline as 8" (I assume double quote meaning inch). Cathay Pacific CX also reporting 8 inch recline. US-based airliner not even attempting to advertise seat recline.
I have heard this recline length is related to maximum horizontal movement of seat during recline action, so I suppose seat height cheating could affect the interpretation.
A picture would be great!
Here is a website compiling seat recline; some have recline in units of length, while others are angle in degrees. I assume that 90 degrees is vertical, but I cannot trust the airline marketing team.
