Applying for shipping space means that the drawer needs to ask the airline for the location of this shipping space. Tickets can be issued as soon as there are seats available. If not, the ticket cannot be issued. Usually this space will be very cheap. Ordinary passengers will want to apply for low-discount air tickets, so the class they get belongs to economy class, and the service in economy class will be different.

Many airlines have frequent flyer programs. These plans can enable passengers to get free travel or upgrade or other rewards according to the mileage of airlines.
