Assumption: in table dimAxeGeographi, ville and region together make the record unique.

Try this:

Merge dim_BTS AS Target using
(
    SELECT A.BTS, D.idVille
    FROM Air A
    INNER JOIN dimAxeGeographi D 
        ON A.Ville = D.Ville AND A.Region = D. Region
) AS Source ON Source.BTS = Target.BTS

WHEN MATCHED THEN
UPDATE
SET Target.idVille = Source.idVille
;

NOTE: It would be helpful if you can post sample data and expected result.
