There are no tickets available in HNA business class.

Hainan Airlines can try the following methods if there is no ticket in business class:

1, contact the ticket agent or travel agency: Some ticket agents or travel agencies sometimes have some unused business class tickets, which can help you find business class seats. You can contact your agent or travel agency to discuss possible solutions.

2. Upgrade: If there are no seats in business class, you can try economy class seats to enjoy better service and comfort. You can ask the service staff at HNA airport to see if there is a feasible cabin modification scheme.

4. Wait for the alternate at the airport: If you come early, you can wait for the alternate at the airport. Sometimes there are some cancellations or changes in a short time before the flight takes off. If you rank high on the waiting list, you may have a chance to get business class.

Business class is more popular than economy class. If you know that you are going to travel soon, you can try to book business class in advance to increase your chances of success.
