A study of the A-supergiants observed with IUE is summarized. Results show that at high resolution they can be divided into two groups: stars which show evidence of wind and mass-loss, and stars which do not show these characteristics. In the first group the resonance lines of Mg II, Fe II, Si II, C II are asymmetric, showing variable blueshifted components. In the second group, formed by the faintest stars, these lines are symmetric. The reported variability suggests a nonstationary structure in the wind of the most luminous A-type supergiants.
