Greeting everyone,

I am quite newto thepoints game. I am planing to visit to Pakistan by Emirates in Feb of 2016. I have over 180000 points that I would like to useto get a returned fare. Here is the break down of points;

Amex 73000
Chase UR 54000
Advantage American airline 64000

I want to know how I can utilize these points to book a returned fare?
How can I gather them at one platfarm.
I am very flexible with dates.

Thank you in adavance for any feed back.
