A couple of months on and I am at the airport again. Asked for a Skyview lounge invite and they said "no we use sats". I asked them why there is air China stated outside the skyview lounge and they told me I could "try".
So I did. And was refused entry (I'm flying J by the way). Argued with them why it states China air outside and they couldn't answer that. Insisted that they needed the invite for THEIR lounge. Finally they let me in... But the issue isn't clear...
But comparing the two lounges, I suggest fighting to get into the skyview lounge
