From seeing the problem, besides not having an online check-in system, Check-in at the counter was delayed because passengers had to check in at the counter only. And you have to come several hours early.
Apart from the lack of an online registration system, Due to passengers having to check in at the counter and having to check in a few hours in advance, check-in at the counter has also been delayed.
It can be seen that except for the absence of online checkout system, the checkout at the counter is delayed, because passengers only need to check out at the counter and must arrive a few hours in advance.
