I have been saying for the last 4 years on how the efficiency here has gone to crap. Seven years ago this company was a machine on how it operated, now we survive on legend it once was. Yesterday, while DH from cvg to tul, we taxied out to 18L, number one for TO we stopped just short of hold short line. WHOOPSS, scheduling forgot our FA!! We taxied back to the gate to get our FA which btw, after looking at her sched. had 5 DH IN A ROW including this one. Yep efficiency at it best. She worked our flight back to cvg, guess what..FA on rids..she DH to stl...Improve the system and stop asking for handouts from the very workforce that allows this airline to operate safely on a daily basis.
