I was there yesterday. Still closed. The checkin agent said that airport renovations caused it. She had no idea when it would reopen.
I was given a lounge pass for the A lounge (as a J pax OWE). When I got there the lounge people said that they had reserved some seats for CX pax, and led me to one of them. This lounge is just ok. It was moderately crowded ahead of the 12:30 CX930 flight. A few scattered open seats only. The food is also just ok. Some Filipino favorites, a noodle dish, rice dish. Quite a comedown from the CX noodle bar. Note that the wine and some other alcohol is at a far corner from the rest of the drink and food setup. Took me a while to notice it. I made do with this lounge but I hope the CX lounge gets opened up again soon.
Priority pass people can use this A lounge or also Marhaba. I went and checked Marhaba and the situation there was about the same as A lounge, without the benefit of reserved seats for CX. About half of Marhaba is reserved for Thai airways passengers. The rest was about the same level of crowded, same catering, drinks, etc. Much of a muchness between A lounge and Marhaba.
The email alert I got (on the morning of the flight) said that the closure was due to a maintenance issue. So there's some confusion about the reason. Maybe the renovations revealed the maintenance issue. Who knows? But it seems CX got blindsided by NAIA about this. It was completely unforeseen.
