I have some B747-100 on order. All configured to 380Y and 24C.
Now, I changed my mind and wanted to reconfigure them. I can't change it for the first 2 aircraft because their delivery is near. That is normal.
Except that 2, all are changeable.
I selected 5, click 'change order' and go to the 'detailed order information' page. I reconfigured them and go for nice price quote.
Weird thing happened here. The first 2 aircraft among these 5 changed order, I got refunded $577 immediately and a $6400 reduction for payment on delivery. The other 3, I got charged additional $1 105 463 immediately and extra $1 652 640 on delivery.
It is weird because they are the same aircraft with same seat configuration which I ordered at the same time and now I change the order at the same time but it need different amount of money. How could it be possible?

But, the new price on delivery are same!?
Bug. Configure the last three after they arrived. You will lose some time, but save lots of money.
