Edit: one more thing, keep your approval email that you received also readily accessible. The airline staff also asked to see my email and opened the attachment themselves. It was part of their process.
I had my own printout but they said they will print me another one and they wrote something on it. Questions were normal like onward ticket, hotel booking, how long staying etc etc.
No ticket and no hotel booking needed. They do ask you in your form the flight number which is like TG434 etc whatever and hotel address which is where I intended to stay.
But they donβt ask you for the actual booking. And it makes sense because before the visa you cannot confirm your flight anyway.
