@djjjaguar64: Thank You. Any reasons why I should select it over Asiana? The miles expire in 3 years thing is discouraging me from joining.

@dvs7310: Sorry for the confusion. I was talking about upgrades paid for by miles.

The AI crediting on L,U,T,S,E classes is 0 for OZ while TK atleast allows 50%.

The redemption rates are also less for TK. An India-US business class seat costs 105,000 on TK while it cost 150,000 miles on OZ.

But reading through the forums I feel that booking award tickets using TK miles is really difficult (trouble with the call centre, going to nearest TK office, etc). So I am confused whether to go ahead with TK or not.
