I booked a joint ticket, and the layover is an hour and a half, is that enough time?

An hour and a half is enough, don't worry.

For a joint ticket, one and a half hours is enough time to go through the transit channel. You can choose to check in directly for the combined ticket and the box, which saves time even more. Hope to adopt!

Hello, if it is a connecting flight ticket, the baggage is automatically transferred and you don’t need to handle it. One and a half hours is enough. If it is not a connecting flight ticket, you can’t delay any time, so please hurry up.

As long as the weather does not affect the normal operation of the aircraft, it is ok

It can only be said to be reluctant, because there are too many unpredictable factors in the plane, this kind of transfer should be done at a small airport, such as Yan'an, Shiyan, and the larger Xi'an and Zhengzhou. There are too many planes at this level, and they are often delayed, at least a little. You don't have enough time for the security check
