Next month I'll be flying coach (for the first time) on the DC-10 from SIN-TYO and need to know which pair of seats are the best? Row 10 A, B, H, J have already been taken up, along with 22 C to G. I am currently booked at Row 22 H & J but apparently these seats are really bad - can someone tell me why? Am I better off sitting in the window seats up front, like row 12 AB etc. ?
