Tickets that are issued slowly will be issued in the end. Generally speaking, as long as there is a ticket in the system, the ticket will be issued after the passenger pays successfully. However, sometimes it may be slow to issue tickets, so you need to wait patiently. If a passenger orders a plane ticket in official website, it will usually arrive in seconds.
But if the ticket is booked from an agency, it may be delayed, and it may take several hours, which is normal. Passengers will be notified directly by SMS after the ticket is issued.
Passengers must pay attention to booking air tickets. For the seats reserved by passengers, the airline has stipulated the time limit for issuing tickets. If the time limit is exceeded, the seat may be taken back by the airline. Generally speaking, the time limit for issuing tickets on weekends or holidays will be advanced, before holidays.
With regard to the time limit for issuing tickets, different airlines have different regulations, and some require passengers to complete payment and issue tickets within a few days after booking. For example, some airlines stipulate that tickets must be paid within 14 days after booking, while others stipulate that tickets must be paid before 14 days before departure.
