There are four Priority Pass lounges in Beijing Capital International Airport. However, Air China’s First and Business class lounges close at 10pm for Priority Pass holders. If your flight out of Beijing Capital Airport is after 10pm, you might want to head to either BGS or BCAT lounges. For me, I decided the latter because it was closer to my gate at E10. The lounge is just opposite gate E10.
Lounge on 3F
The lounge is on the ‘second’ (3F) floor. So you will need to take a lift. Interestingly, the lounge is not really a lounge. It doubles up as a lounge in this hourly-rate hotel.
My flight was at 1am. When I got to the lounge at about 11pm, the staff told me there was no more hot food and asked whether I was okay with snacks and soft drinks. I just needed a place away from the hoi polloi so food wasn’t my priority although it would have been nice to add it to this review. Anyway it was already late and I had dinner.
Soft drinks and some chinese snacks were there. They have instant noodles too but you will have to ask that from the staff. I guess it was to prevent people from ‘stealing’ hence they were not displayed on the table.
Looking out from the lift towards gate E10 
This is how the ‘lobby lounge’ looks like. There is no boarding announcement so you have to keep an eye on your flight.
This door leads to the hourly-rate hotel rooms.
A glimpse of dinner if you were at the lounge between 5-7pm.
Toilets were clean and I love the porcelain basin! Unfortunately I cannot recall whether there was a shower facility.
If I had a choice, i wouldn’t use my Priority Pass to come in here if not that it was next to my gate. The security checks earlier was horrific enough hence i needed a place away from the crowd. The lounge was sparse and to say that was already a compliment.
Air China First and Business Class lounges would be my choice but they do not accept PP after 10pm. I have yet to try BGS which i will at the end of the year where I will transit through Beijing Capital Airport again. Stay tuned.
