We present the results of the first observations, taken with FLAMES during Science Verification, of red giant branch (RGB) stars in the globular cluster NGC 2808. A total of 137 stars was observed, of which 20 at high resolution (R=47000) with UVES and the others at lower resolution (R=19000-29000) with GIRAFFE in MEDUSA mode, monitoring ~3mag down from the RGB tip. Spectra were taken of the H{alpha}, Na I D and Ca II H and K lines.
