It's a 343 and they moved me from 3 H/K to 15 H/K. I have been changed back to 3D/G and 3 H/K. These are jmo in terms of seat quality, however. Others may feel differently. But I made these seat assignments last February and it's not like they are bassinet seats which need to go to mothers with children. They obviously allocated them to someone who booked much later than I.
