Reasonable time frame

[caminojune2017]

If I fly into Paris at 620a, is it reasonable to book the 840a flight from CDG to Biarritz? Seemed like plenty of time to me.

If your flight is on time, it should be enough.

Would this be on two separate bookings? If so, and if your flight is delayed or if either flight is rescheduled giving you less time between flights, causing you to miss the flight to Biarritz then you will have to purchase a new flight. The airline will not be responsible for rescheduling you.
Also, it depends on where you are flying from and if you need to hold through customs and immigration.
