Lastly, don't be afraid to ask about safety: Any reputable operator should have safety information prominently featured on their website, and won't mind answering questions about their pilots, such as how many hours they have flown. (At least 250 hours, which is what it takes to get a commercial license; NetJets mandates at least 2,500 hours; Wheels Up, mandates 7,000 hours for a captain and 4,000 for a first officer.) Gollan suggests fliers ask if the pilot has any health issues, and feel free to ask if the operator (or plane itself) have any accidents or incidents in its history.
