In addition to the FTers’ popular single seats in the odd rows: 3, 5, 9, 1 (not for me ever again), I would like to share that I have grown to like 17A and 17L.
Yes, row 3 and 5 in the front cabin are popular, but there is still a lot of foot traffic between the two galleys and restroom areas. I have found little foot traffic sitting in row 17. The only foot traffic is from row 18 (last row of Polaris cabin). My best rest and sleep have come from sitting in row 17 window seats in my over 20 United 777-300ER flights.
