Tips

Three ways to help avoid delays: fly first thing in the morning, take nonstop flights, and travel via less crowded airports). If nonstops aren't possible, try to connect through a warm-weather airport, such as (Dallas, Houston, or Phoenix, rather than Chicago or Minneapolis),
where weather-related delays are more likely in winter. If you're
connecting, it's even more advisable to fly as early as possible in the
day, before delays have a chance to build up across the country. Check
out Flight Stats to research a route's on-time record, and the Transportation Security Administration's "Wait Times" section if you're wondering how long it takes, on average, to clear airport security.
