At the airport, December 20, 21, 22 and 23 are notoriously busy for travel to just about anywhere. Just thinking about days like that led me to write the Holiday Air Travel Guide.

I wrote and compiled the Holiday / High Season Air Travel Guide to cover some of the important aspects of traveling during this time of year - from finding airfares, to the airport experience, and what happens when flights delay and cancel.

The topics covered are - searching for cheap airline tickets; travel with infants; travel with pets; online check-in; luggage fees and allowances; what kids can do at the airport; TSA Secure Flight; airports during peak travel periods; rule 240 and canceled/ delayed flights; what to do when flights cancel because of weather; travel health tips; and travel comfort tips. Hope it helps make your holiday travels a bit easier.

It's been a rough couple of days - not only with historic snowfalls hitting parts of the Eastern seaboard of the United States, but inclement weather and bone-chilling temperatures across much of Europe.

So what to do if an airline cancels your flight due to weather? As someone who has worked at the gates and announced the bad news on countless occasions, here is my guide to what to do when a flight cancels due to inclement weather conditions.

Also, I do try and keep up with current weather issues (and feel free to post any weather-makers that may affect air travel) in the Air Travel Forum - Weather and the Airlines.
