Can air china economy passenger purchase a pass to the Chengdu VIP Lounge?

I'm afraid not. I heard it is only for first class ticket holders and business class ticket holders. Anyway, to confirm that, you can dial 028-85206150 to consult. Apart from that, there is an Airport Express Hotel in the east of T2, where u can have a safe rest.

Thank you for the information about the nearby hotel. The lack of non-smoking rooms would be a problem for me. Any suggestions regarding that?

If you are referring to the non-smoking rooms in the hotel, it is suggested to consult the hotel on the spot.

If you are referring to such spaces in the airport, call 028—85205555 to ask.
