Pick your top travel companies. This includes the airlines and package airfare sources you use the most. Whether it's airfare or hotel deals from Travelocity.com or TripAdvisor.com, get on their mailing lists. They will alert you to the latest and greatest deals and discounts, which allows you to stay on top of the pricing trends.
Sign up for trip planning resources. There are a variety of resources on the Internet that will cater to your every travel question or desire. Some of these resources come packaged in with other websites, like Orbitz.com, and some sites are dedicated exclusively to the planning and execution of trips, like LonelyPlanet.com or Couchsurfing.org. These sites have forums where active discussions about specific travel concerns take place every day. These updates can arrive directly to your inbox if you choose.
Use RSS Feeds. This is one of the easiest ways to receive exactly the type of news you want. For Microsoft Outlook users, RSS Feeds appear in a separate part of the inbox, which helps differentiate between everyday correspondences. Most every major publication and company offers RSS feeds, so the choice is really up to you: The Travel Channel, USA Today, CNN and The New York Times all have RSS Feeds specific to travel news and updates. For international alert and safety concerns, sign up to the US Dept of State RSS Feed.
