As a person who flies sporadicly to no predictable locations, are Avios a recommended program to credit my AA flights to, considering their longer expiration policy, and their ability to transfer to Iberia? If yes, I am flying a short TW flight with AA soon, should I credit the flight to Iberia or BA? I currently have no activity on either, and I want to be eligible for transfers between the two. Also, I will get a small bonus (200) if I show activity on Iberia within 30 days.
I am new to this forum, so I apologize for the freshiness, and for not being able to contribute much yet.
