use avios only or use avios plus $$$

[mitzeahnow]

I am purchasing two one way tickets with avios.
The money purchase price is $300/ ticket or $600 total
 
The Avios price options
20000 Avios + $ 108.36
18000 Avios + $ 138.36
16000 Avios + $ 168.36
14000 Avios + $ 188.36
12000 Avios + $ 218.36
10000 Avios + $ 238.36

I was going to use only avios and pay the $108.36 mandatory fees, but then I calculated that it was only $130 to buy 10000 avios  or 1.3 cents/avios
I am pretty sure i can use the 10000 avios in a way where I will get more than the $130 that it cost me.
However since amex mr points transfer in now at 1.35 that means I am paying 1.75/mr 
Anything wrong with my calculation?

What would you do?

[Ergel]

Is this for each ticket or total?

[EMES]

Is this for each ticket or total?

looking at the taxes it should be for both

12000 Avios + $ 218.36

It depends what avios are worth to you and would you rather spend the $ or the miles.
