I have a flight booked as a BF from San Diego to Zurich via Amsterdam and Houston. On the return trip, there is only a 1 hour time connection between flights in Houston to return to San Diego. Is this enough time considering we probably have to clear customs in Houston? The next available flight to San Diego would not be until the next day. The ticket agents at Continental didn't think this would be a problem but I'm concerned with a possible delay due to weather, air traffic, etc. Has anyone had any experience catching the connecting flight back to San Diego?
