I wonder if this arrangement would be considered sterile enough for OSS purposes. Passengers from non-OSS countries are
not re-screened when transiting through T1. There is inter-mingling of passengers from all origins in the international departures area. In contrast, airports like MUC and ZRH are able to completely segregate passengers from OSS vs non-OSS origins.
