Which is better, Hainan Airlines or Air China?

Maintenance: Air China's aircraft have undergone strict maintenance to ensure the safety and performance of the aircraft. Air China also has a more perfect maintenance system, which can find and solve problems in time and ensure the normal operation of the aircraft. HNA does not have as many maintenance points as Air China, which makes it impossible to repair some parts quickly.

Model update: Air China is one of the three major domestic airlines, with relatively stable financial strength and operational capacity, so the aircraft is relatively new, and many models, such as A350, have been introduced in recent years. These new models have more advanced technologies, such as more advanced communication and navigation systems, more comfortable seats and spacious seat spacing, which can provide passengers with a safer, more comfortable and more convenient flight experience. As a private enterprise, HNA is not as rich as Air China, so the model update is slow.
