The number of travel hacks that have been touted across the Internet as “the way” to get the “best” deal have many chasing the potential for something that isn’t out there.

For example, none of these well-publicized travel hacks for getting a cheaper flight — clear your cache to avoid high airfares, don’t use a Mac, buy 42 days in advance, book after midnight on a Tuesday — actually work.

If you want to get a deal on an airfare, don’t book too early or too late. Booking one to four months out should result in a decent price. And the differences in between prices are not so vast anymore either. You might save $40 or $50 on a discount site, but you may be penalized by not being allowed to select your seats or being more likely to get bumped if a flight is overbooked.

As for booking the best hotel rate, don’t believe the hack about calling the property directly unless you’re negotiating a group rate for a special event. That’s another situation entirely. If you’re thinking that you’ll be able to use your amazing negotiating skills if you can just speak with a human being, think again. Calling a property directly will most likely end up in a reroute to a reservation center. Just go to their website and make sure to enter your loyalty number. If you don’t have one, join their loyalty club and then stick with them for future travel. That will always get the best rates.

Finally, if you don’t join a loyalty club and every dollar counts, check a meta-search website instead, such as Google or Kayak.com, Booking.com, or Expedia. Cross-check your findings with those of the hotel’s website, though, so that you don’t miss a deal there.

“Tipping” the front desk personnel when checking is another travel hack that usually doesn’t work. Most often, the employee keeps the money, not understanding that you were attempting to hack the system and get an upgrade. This does have a better chance of working at fancy hotels in big cities, but even then, it doesn’t always help.

Rental cars used to be able to be procured for deeply discounted rates by making a reservation via travel sites like Travelocity, Hotwire, Orbitz, or Priceline. Not so anymore. The best deals today are through Costco, AAA, or the rental companies themselves, such as Hertz, Enterprise, National, Avis, and Budget.

If you need an inexpensive rental car, start with the rental companies’ websites, but check the other sites as well. The rental car companies truly have figured out that it’s better to offer great deals directly to their customers than to make them hunt them down on competitor’s sites.

Everyone wants to figure out a way to hack the system and travel cheaper or faster. While it may seem innocuous at the time, many potential hacks may involve lying, bribing, or cheating, and those behaviors only end up creating consequences for the traveling public—often resulting in higher fares and tighter restrictions. So be careful in the hacks that you use.

Your best bet is to join loyalty clubs at your favorite hotel, airline, and car rental agency and stick with them as much as possible. Also, get a credit card that rewards you loyalty points. Your membership in those clubs can get you some extra perks.
