I have an upcoming work trip to Japan in J on LH metal ticketed through ANA. Based in France *A services don't really work well for me and normally use either AFKL or LCCs for all my work trips
Consequently, i have no *A program and realistically it's quite unlikely i'll start using *A with any increased frequently in the future. However, i don't want to waste the opportunity to earn, especially with good potential on these business flights just in case i can use it in the future.
Any suggestions of a program i could join to credit this too?

(1) What is your home airport? NTE/BOD, CDG if i have to
(2) What types of fares do you usually buy ? Economy, which ever class my company books and pays for
(3) How many miles do you usually fly each year? probably 15 returns in EU a year
(4) Do you have any kind of status at present? What is it? none (in *A)
(5) What is most important to you in a FFP? priority airport services (boarding, security, passport control), Lounge access
(6) Which routes do you fly most often shorter 4-5 days trips within the EU
(7) Preferred Airlines none in particular
(8) Do you travel for work or pleasure? work generally, company specify economy only Schedule and connections don't make it very easy to use *A
