Does Rasa support follow-up intents

Does Rasa support follow-up intents? Ex: Chatbot booked an air ticket for me. Now it should ask followup questions like. Do you need airport transfers?

Yep, you could do that within a single Form and just ask for additional services before booking the flight. Or you could send an FollowUpAction with the end of the first form (after the flight was booked), that handles additional services.
