Is there a plane from Guiyang to Haikou? How much is the charge?

Yes! In the Spring Festival of 2008, I got a special price, which was direct flights from Haikou to Guiyang and 290 yuan. It can't be so cheap now. You can try to check the specific fares of Ctrip.com and Qunar.com. In April this year, I bought a round-trip ticket from Guiyang to Haikou in May, 920 yuan (including the fuel fee for airport construction), but I stopped at Nanning Airport for half an hour, not a direct flight. The premise of such a cheap fare is that I booked it one month in advance! I bought it on Ctrip. Make an appointment directly by telephone, and then go to meilan airport and Longdongbao Airport to get your ID card for registration.
