Singapore Airlines (SIA) operates in Muscat, Oman, primarily through an appointed general sales agent (GSA) or partner like Dnata (often handling bookings, changes, support), rather than a standalone corporate office, so for official contact, you should use SIA's global contact center numbers or visit their official website's support section for local Muscat details or booking assistance via phone/chat.
