I really wanted to make this trip via train, but it seemed difficult to book a ticket on short notice, plus the extremely helpfull staff at the Traffic Hotel in Chengdu where pretty keen to suggest the plane was going to be the best option.
So the flight was booked, with the cheapest option at that time being via China Southeast Airlines (China Southern).
Chengdu Airport isn’t huge but it sure gets busy. I booked a private car to take me straight to the airport, it seemed like simple no fuss way to go and it was comparitively cheap. I remember walking into the airport and just being daunted by the sight of so many rows of people, and how many people there was in each row lining up to check-in.
