I dislike the reference to "Ground Service" as, in aviation circles, that usually encompasses baggage handling and delivery, passenger boarding and coach operations, tugs, ground power, aircraft stairs and other things that go on "on the ground".
"Check In" is usually referred to as just that, "Ticketing and Reservations" another and "Lounge Dragons" yet another topic of conversation.
Final Three Greens latest complaint against big bad BA centres around "Tickets and Reservations" (or "contactba" as marketing have called it.)
Mistakes do happen, it's human - otherwise the manufacturers of "Tipp-Ex" would have shut up shop years ago.
BA can stop threads such as this very easily, by doing things right, first time.
Is basic competence really too much to expect?
Does any business live up to your exacting specification, FTG?
