Avoid Flying on the Weekends
Don't groan. Weekend airfares are more expensive because there's heavy competition for those seats. It's hard to sacrifice a whole vacation day to travel during the week, but you can save money and probably some hassles as well. Avoid that block of time from Friday afternoon to Monday morning. Think of it this way: If you travel during a weekday there'll be fewer lines, people will be less stressed (and therefore more genial) and you'll have a little extra time to do things like pack efficiently and remember to take out the garbage before you leave home. The plane may even be less crowded, which means you might be able to get through the first leg of your holiday without having to apologize (much) for anything your darlings may do during the flight.
