If you have enough miles(min 15000)in kuwait airways, you can redeem on their website Roundtrip(only).

Else you have miles for oneway or roundtrip to approach kuwait airways office in your country to redeem by paying taxes. Very useful.

Else check for travelling class upgrade on your future trips.

If miles are about to expiry then you can buy oneway or roundtrip tickets to others too...(including me...haa haa).

I am living in kuwait for past 6 years. If you are residing in kuwait, this is the best program to opt.
