The Marhaba (formerly a Dnata lounge) – also the Priority Pass lounge at Singapore Changi Terminal 1 is located directly above the Departure Immigration Area of the Departure Transit Hall. Proceed through Departure Immigration, take the escalator to one level above. It is right beside the Qantas First Class Lounge. This lounge is located at the airside which means it is available to transit passengers.
The lounge is much bigger than other Marhaba lounges in Changi Airport. If you have more than a couple of hours in between transit, i would recommend this lounge for space.
Food is fair not great but they serve barista coffee – unfortunately it was closed when i was there at 10am. There is a drinks counter right at the other end of the lounge, which is great because you don’t have to walk to the other end every time you need a drink.
The toilets and shower rooms.
