Turkish Airlines Miles & Smiles is running a promotion with a reduced mileage requirement for certain economy class redemptions.
Miles & Smiles has a pretty generous award chart, but I struggle to easily generate miles in that program. I have started crediting many Avis rentals to it (500 per rental) but it takes 8-10 weeks for the credits to show up.
Miles & Smiles is not a transfer partner of Starwood or the US credit card programs either.
Do you have a better strategy?
