Looking for cheap air tickets from Nanning to Beijing

Generally, half a month in advance is enough. If you go too early, it may not be cheaper. The fare changes from time to time, so you must sell it immediately if you are sure. Don’t choose peak seasons, such as New Year and holidays. Many websites nowadays have very good services, such as eLong Travel. My friends and I have been buying there, and the after-sales service is also good. However, special air tickets, that is, cheap air tickets, have three no-no restrictions, so if you buy them, you must take them. Otherwise, you will suffer a big loss. It’s also a good idea to buy tickets on airline websites.
