I've been to the country a few times now and hated every second of air travel there, it's messy, people behave really badly regarding rules and pilots are always changing altitude/speed during (supposedly) level flight to the point that you feel like you are on a rollercoaster.
In comparison train travel is incredibly pleasant and efficient, albeit sometimes quite busy. I know this is going to be an unpopular opinion but many countries in the West should hire the Chinese to construct and build HSR in their countries with foreign labour under local direction. The benefits are huge for rail. Airports for short journeys just seem wasteful and incapable of dealing with climate change problems. Not to mention the stress of security hassles.
Here's the last 12 years of rail in China: https://image5.sixthtone.com/image/5/4/861.gif
In Australia we have been debating the high speed rail issue and doing feasibility studies for two decades now. The cost of AUD $100 billion was considered to not be worth it. Federal covid cash handouts to individuals in the last year alone topped $200 billion.
