Flight delays are out of your control, but finding comfort while waiting could be in your hands. Depending on the length of your layover or delay and the time of day it occurs, you might consider becoming a VIP. It's not uncommon for airlines to sell one-day passes to their VIP lounges, where you'll find a more comfortable atmosphere than the bustling gates, Internet access, and refreshments.
The passes aren't exactly cheap — Delta charges $50 for a one-day pass — but the cost could end up being completely worth it depending on the status of your flight. Keep this option in mind when you're traveling during particularly busy times like Thanksgiving, when weather and flight schedules can be more unpredictable than usual.
