Under which policy can carriers fly where they choose, charge what they wish, and make deals with each other?

• A. Open-jaw trip
• B. Overbook
• C. Paper ticket
• D. Open-skies policy

Answer: (D)

Open-skies policy liberalizes international air services between countries, giving airlines freedom to choose which routes to fly, how much capacity to offer, and how to price their services with less government intervention. It often includes protections that let carriers form alliances and cooperate on schedules, revenues, and even code-sharing, effectively enabling them to make deals with one another across markets. This is what lets airlines operate more flexibly and coordinate internationally.

An open-jaw trip is just a type of itinerary, not a policy about market freedom. Overbooking is a common practice unrelated to broad regulatory liberalization. A paper ticket is simply a form of ticketing, not a policy framework.
