Passenger Seat Number X

Song hates the rainy season. Rain reminds him of a day he once spent stuck under the sky with someone he loved. In Passenger Seat Number X (คุณผู้โดยสารถ่านไฟเก่า) that someone comes back at thirty thousand feet, sitting among the passengers and holding the keys to the whole airline.

Song, played by Chawarin Perdpiriyawong (NuNew), has worked as cabin crew for Silver Lining Air for two years. Work fills his entire life. He calms rowdy passengers, solves meal shortages with a smile and turns down every invitation from colleagues who tease him about marriage.

Then Jirapat Keeratithavorn, called Pat, steps on board. Played by Pruk Panich (Zee), Pat is introduced to the crew as the new CEO of Silver Lining Air. To everyone else he is the boss. To Song he is the man who once gave him a ring and asked him to wear it at all times, with a promise that Song would repay it whenever he had saved enough.

The two broke up because Pat's parents opposed the relationship, and Song refused to let Pat throw away his family and future for him. Now Pat wants another chance, Song insists the past is over, and the ring he once swore to wear says otherwise. Yanin Opassathaworn also joins the cast. With your ex on board as a passenger, even the drinks trolley feels like a test of nerves.
