I have booked a flight to Madrid on Sept 13 from North Carolina. In the past, I've had no issues booking flights further north to start my camino. I'd like to stay in the T4 terminal. My flight is scheduled to land at 6:40 am. Iberia has a flight to Santander but it takes off at 7:40 am. Is this enough time for customs and getting to my flight? I really want this to work because this camino is more restricted time-wise than previous caminos.
