Your 744 and 346 seatmaps warn about IFE boxes on many VPORT economy aisle locations D & G. Do all the D & G seats in those economy sections have the IFE boxes? Do the C & H aisles also have IFE boxes? I am planning for seat selection on future Virgin LAX-LHR-LAX flights, and curious about avoiding the IFE box, while still enjoying an aisle seat.
I can confirm on the A346 that the aisle seats C & H does not have the IFE box under the seats because the boxes are located under window seats A & J. I had a 'H' seat on both my outbound and inbound flight of my recent trip and is perfectly fine. I strongly suggest you dont get the seat with the IFE box.
Happy Flying
