There are actually Skywards folks within the T3 Business Lounge. Have your Mum go there and they should be able to update her status immediately.

If the front desk wont let her in, there is a side door - further along the corridor and she can walk down there. All she needs to say is that she wants to see the Skywards folks and not enter the lounge.

They're actually about 4 small round tables, staffed by EK folks with small Skywards signs on each table.

A friend recently flew with me from JFK to DXB and that flight made him Gold. He simply went to the Skywards desk and they updated his status immediately. He then got op-upped to J for his connecting flight to BKK (so he was a happy camper).

Your mum could also try having her status updated at the T1 lounge opp G122 - but I'm not sure. Tell her to persist with either lounge, especially if she has a long layover.

Let us know how she gets on or if you need any further help.

Remember, if she goes to the Skywards desk within the T3 Business lounge and they update her status, she will have to technically walk back to use the lounge for Silvers, opp Gate 122.
