We are STRONGLY advising all travelers to arrive at the airport at least 90 minutes prior to scheduled departure time in the summer or when the weather is good in the winter, but at least 2 hours is strongly encouraged, especially during bad weather. In the event that Mother Nature intervenes in your travel plans, you will be contacted by your air carrier, who will provide you with information regarding alternative transportation to another airport, so that you will still arrive at your destination on time.
