Just a pity the SABRE check in product is absolute rubbish compared to Altea CM - in fact, it is YEARS behind even DCS such as BABS and QUBE or even Air NZ Carina.
Other systems have the same connectivity as you detail, but have airport departure control that is a million years in advance of SABRE Interact.
SABRE Load Manager is apparently worse, it is barely more useful than an Excel spreadsheet.
So, BAD move VA.
