The 747 IMO is the most beautiful aircraft ever, certainly the most beautiful civilian aircraft.
A couple of years ago, I made it a point on an international trip with my kids to book seats for us on the upper deck. It was really awesome, and I am sure they will look back on it as a great memory.
If you are able to, before it is too late, I would encourage doing it.
The most iconic seats on the most iconic civilian airplane!
