Which airport are you departing from

[NamelessKing]

Which, if any, of the following questions is the most natural in a casual conversation?

1. Which airport are you departing from?
2. Which airport are you leaving?
3. Which airport are you flying from?
4. Which airport are you taking off from?

Can you suggest a better alternative?

Where are you flying from?

Where are you flying from?

Thanks, but I think that question is too general if I want to know the name of the airport. The person I'm asking could respond, for example "I'm flying from New York" but there are about four airports in the city.
