By how many minutes should service delivery in Delta Main begin after takeoff, flight conditions permitting?

• A. 10 minutes
• B. 15 minutes
• C. 20 minutes
• D. 25 minutes

Answer: (C)

Service delivery in Delta Main is designed to begin 20 minutes after takeoff, provided that the flight conditions allow for safe operations. This protocol is in place to ensure that the cabin crew can effectively manage service logistics while ensuring passenger safety and comfort. Beginning service delivery too soon may interfere with flight crew duties and may not account for any immediate needs related to takeoff turbulence or other conditions that might require the crew's attention. Therefore, the 20-minute mark provides a reasonable timeframe that balances the need for timely service with the necessary caution during critical phases of flight.
