It is a contender for best overall
SkyTeam mileage program.
Not exact matches
It's best to start with one
mileage program in each of the three alliances: Star Alliance, OneWorld, and
SkyTeam.
Mileage redemption can be done using the Delta SkyMiles
program as Air France is a founding member of the
SkyTeam alliance of which Delta is a member.
However, all three
mileage programs are very different with Delta being the sole carrier that's part of an airline alliance (
SkyTeam).
In fact, their partner airlines are so vast that by crediting points to
Mileage Plan you are essentially getting the best of
SkyTeam (if there is such a thing) and the best of OneWorld in one
program.
