Caveat to the answers used to be AA EXEC PLAT for the past 10 years.

Given the revenue imposed DECIDED TO SWITCH

Home base is BCN. But have homes in MIA and PDP (Punta del Este, Uruguay). So travel often to the US and South America. Once in the US or South America do need short trips (US, EUROPE). Having tracked offers to South America AF-KLM paying with AMEX gives me a very reasonable fare for 2 (around 3600EUR).

Pay for my own tickets (there are 2 of us plus GUIDE DOG).

Ability to transfer CC miles is also important currently AMEX PLAT and IBERIA Sendo (only for those places that will not accept AMEX).

(1) What is most important to you in a FFP?
Soft expiry, Link to Credit Card, lounge access, ability to redeem miles (must say 90% of the times in the past have been able to secure OW award tkts for the routes that was looking NOT SURE WILL HAVE THE SAME LUCK WITH SKYTEAM)

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
Managed to fly 100K on AA

(3) What types of fares do you usually buy?
Used to buy mostly cheap economy fares but gradually moved to mostly or mixed J W

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
YES. Pleasure and Work

(5) Which routes and airlines do you fly most often?
BCN-US, BCN-MVD, BCN-ASIA (pleasure and biz). Can easily position in order to get a better PREMIUM fare

(6) What is your home airport?
BCN

(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
Downgraded to gold on AA have some miles left

(8) Preferred Airlines? Most common Airlines flown on?
AA, IB, QR

Having said that my analysis has shown that AA will no longer suit me, seems that best bet is FLYING BLUE

This year my heavy travel will elapse into 2018 BUT GIVEN THAT FB GOES ON A CALENDAR YEAR will leave me with no elite status with them until at least mid 2018.

Let me know if I have missed anything and thanks in advance.

Best, JC
