Traveling can be one of life's greatest experiences, but if things go wrong, you might wish you had stayed at home. In an effort to help you spend less and stress less on your next vacation, the London Luton Airport has created an infographic containing helpful travel advice.

Some of the tips are gentle reminders—like book your flights early, avoid peak traveling seasons, and please be nice to the airline staff—while others are less obvious. For instance, it's best to avoid flying over a seven-night block of time. If you book flights over a period of six or eight nights instead, "you've got a better chance of scoring a lower fare," the airport claims. (Also worth noting: If you're flying domestic in the U.S., the cheapest days to travel are usually Tuesdays, Wednesdays, and Saturdays, according to Fare Compare. For international flights, weekdays are typically cheaper, although it depends on the exact route.)

In general, anything you can take care of in advance is a good idea. Check to see if you can get a better parking rate by pre-paying online, and take the time to apply for a TSA PreCheck. It's easy to do, and when it's all said and done, you'll be able to join the express line at airport security. If only Starbucks had a fast lane, too.
