Both dramas are about aviation industry and chasing your dream. Nine Kilometers of Love focus on the aviation academy, while Flight To You showed all about the whole industry. (Ground Crew, Cabin Crew, Pilots, Mechanics, and the Administration).

Both dramas have different story but the similarities that I noticed were:
- The male leads got frame up and was sent to jail.
- The secret lab
- A psychopath serial killer

p.s. also watch Danger Zone S2: The Silver Lining bcoz it's the continuation of the story.

Both thriller movies are about a crisis that took place at 36,000 feet. One is about bioterrorism while the other one is when the cockpit windshield blew out. They both tell what happened when a flight was forced to make an emergency landing.

Both are disaster-themed movies where they need to save people who lives near the vicinity. One is a nuclear power plant while the other one is oil depot.

Both dramas have a similar concept which is the gaming world. The characters have to use their superior problem-solving skills and intellect to win the challenges in order to survive.

The both have a similar plot where the male lead has a sick grandparent who wants to see him fall in love and marry a girl so they end up having a contract marriage.

They both have a similar plot, achieving one's dream in aviation industry. One is based on how to be a cabin crew while the other one is how to be a Pilot.
