Any recommendations for the most comfortable seats for a 15-hour flight on the 777-300ER Premium Plus? It is 3 rows, 20, 21, and 22, with a 2-4-2 layout. Right now the available seats are row 20 seats B-G, 21 E-G, and 22 A-G.

Also, recommendations for the best seats for quiet and hopefully some sleep on a 14-hour flight on 777-200 Business Class. 8 rows in the first cabin and 5 rows in the second cabin, with a 1-2-1 layout.

Thank you
