If everything is going well and without any problems, we can say it’s ‘smooth sailing.’ For instance, ‘The flight went smoothly, and it was a case of smooth sailing.’

When someone is extremely happy or elated, we can say they are ‘on cloud nine.’ For example, ‘After the successful landing, the pilot was on cloud nine.’

4. Red-Eye Flight
A red-eye flight refers to a late-night or overnight flight. For instance, ‘I’ll be taking the red-eye flight to New York tonight.’

When someone is in charge and makes the decisions, we say they ‘call the shots.’ For example, ‘The captain is the one who calls the shots on the aircraft.’

Turbulent times refer to periods of difficulty or uncertainty. For instance, ‘The airline industry has seen its share of turbulent times.’

If someone is doing something without a plan or relying on instinct, we can say they are ‘flying by the seat of their pants.’ For instance, ‘During an emergency, pilots sometimes have to fly by the seat of their pants.’
9. In the Loop
When someone is kept informed or included in a decision-making process, we say they are ‘in the loop.’ For example, ‘As the co-pilot, it’s essential to be in the loop about any changes in the flight plan.’
