Information supplied to the GDSs for Air Zim :
UM 722 ops WED SUN HRE I LGW S 0900 1830 eff 03JUL13 EQP=762
UM 725 ops TUE THU LGW S HRE I 1930 0630+1 eff 01JUL13 EQP=762
Which implies a positioning flight HRE LGW and that it will sit at LGW from 1830 on SUN to 1930 on TUE. Maintenance?
Somehow I don't think this will happen.
