Can I make a reservation first and purchase the ticket later?

For the following reason, reservation and ticket purchase should be made at the same time in our homepage.
JINAIR operates a simultaneous purchase system to establish aviation reservation culture.
This is to reduce NO SHOW rate and to give more booking chance to actual requirements.
So we need to keep actual booking data in our booking system.
It might be inconvenient, but ultimately it's more efficient to use air seats for the convenience of our customer. Please understand our policy.
