Can I go through express security check for Osaka Spring Airlines exclusive flights?

No. Exclusive Fly is Spring Airlines' former business economy seat. By purchasing its ticket, you can enjoy exclusive front-cabin seats, private space, wider seat space, more free baggage allowance, points refund, and more flexible cancellation and change rules. Go through the express security check. Private space means that there is a special curtain between the premium flight seat and the rear seat, allowing you to enjoy a quieter personal space in the front cabin of the aircraft.
