It is true that these fuel surcharges AC uses have always been higher but it has gone up even from last year.
The higher fees in J point tickets (no diff in fuel surcharge) and the overall higher fees in Y and J suggest a)linking to fees on rev tickets which include tax and b)a signficant increase from last year when Y and J were both consistent in the 400 range on the TATL route. It has gotten even worse.
Thanks AC!
