A pairing can range from how many days?

• A. 1-3 days
• B. 3-7 days
• C. 1-5 days
• D. 5-10 days

Answer: (C)

Pairing duration is the span of a crew’s scheduled work from the first flight of the trip to the return to base. The standard range is 1-5 days because most crew trips are short enough to be completed within a few days while still allowing proper rest and fit with scheduling cycles. This window covers common domestic and short international itineraries and helps manage fatigue by keeping rest periods aligned with crew rules. Longer trips (beyond five days) exist in some cases but are typically treated as different trip types rather than a single pairing. That’s why 1-5 days is the best answer.
