When Mike asks the Thai officer if he will take a company card (after showing his old CIA business card) for a plane it's similar to when Harrison Ford's Jack Ryan asked the owner of a helicopter if they would take a company check while doing the same in Clear and Present Danger (1994).
The title character's given name is John Patrick Ryan. Jack is a nickname.
The fighter jets in the hangar when Jack meets Cathy and Greer are Swedish multirole fighters JAS 39 Gripen used by The Royal Thai Airforce.
In the final scene the name block on Jack Ryan's desk says John Ryan.
