So I am considering booking a HOP flight from Marseilles to ORLY on 6/2 as a back up to a scheduled train, I have never booked a refundable flight in my life. Any ins and outs I need to be aware of? Any Fine print? I assume I can cancel anytime without penalty up to flight takeoff? If I read correctly I can cancel even after takeoff (assuming I'm not on the fight). Seems like a good backup plan.
Thanks is advance!!
