We discuss photometric monitoring (VBLUW system) of three B[e] supergiants. All three objects appear to be variable. They are subject to two (R 66 and R 126 in the LMC) and three (S 18 in the SMC) types of light oscillations which range from a few days to years, and are probably due to pulsations. We argue that a classification as α Cyg variables is justified. Their classification as mixed B[e]/S Dor variables is less certain, though not impossible. Also based on other cases, a strong B[e]–S Dor variable connection seems to be present.
Key words: stars: variables / stars: supergiants / stars: individual S 18, R 66 = HDE 268835, R 126 = HD 37974
