I booked on the Flying Blue link website, like last year, and nothing has posted correctly. The base miles 3rd, 4th and 5th rentals have not posted whatsoever.
I wonder if it is perhaps a good idea to do an online retro-claim for the base miles before chasing the Accumulator bonuses up. Then at least you have the base points there (online booking and Gold member bonus, 100 extra miles each, have not posted for me at all).
Surely no-one here thinks this is worth the bother considering the latest devaluations? The only thing I would do with them is two 50% Economy Promo redemptions to somewhere in N America.
