hallo..is there flight from Guangzhou to Zhangjiajie?

Yes, direct flights are available for this route. The Tianzishan Cable Car is under maintenance and it is expected to reopen in Oct. 2015.

For package tours, I know that TravelChinaGuide can arange this, but I have no idea of the quotation. You can contact them by traveltravelchinaguide.com to get more detailed info or just fill the enquiry form online.
