Does anyone have experience has to how much time to allow between flights in Madrid airport? The flight I am looking at has a 70-minute layover before I need to connect with another flight to Jerez. (I will be flying from Newark to Madrid.) In the warning, it states that 70 mins. is a tight connection, and a missed flight will be very inconvenient. What has been your experience going from an international arrival to then departing to another Spanish city? Thank you for your help.
