A movie about flights starring Liam Neeson

It's "Rapid"

Liam Neeson is an air marshal on a flight. During the flight, he received a series of mysterious text messages asking the government to send money to a secret account. Transfer 150 million US dollars, otherwise the other party will kill a passenger every 20 minutes, so Liam Neeson and the other party launched a wonderful battle of wits and courage at an altitude of 40,000 meters
