Which airlines FF programme for miles
 

Hello,

My sky trips have never been frequent and mostly on short distances, so I never have been in any frequent flyer programme. Now it has changed a little bit. I will be having around 3 trips per year, from Japan to US and Europe and my first will be on this Monday.

The trips are not frequent, the distances are significant, so which airline frequent flyer programme do you advice me to participate in? It seems that maybe Delta has the best miles reward for a person such as me, who will be travelling in economy class on cheapest tickets. And my trip on Monday is going to be with Delta. However I am completely new to the subject.

Thank you for any advice.

Yes, delta seems to be a reasonable choice due to your cheap Eco long-haul flights and you wont have a problem with miles expiration.
In any case Asian programs and AF/KL's Flying Blue wouldn't be good choices.

Thanks, so I will try with delta.
