Most airlines make you join their frequent flier programs in order to get email deals, but they’re usually free to join. Many airlines will also give you free miles/points just for signing up. Some give you points for doing surveys or sharing the program on social media.
Organize the travel deal emails and keep your inbox clean by creating a filter and adding each email address the first time you receive an email from the airline, hotel, or other travel provider. Gmail makes this process very easy, but you can also do some basic filtering with with most other email providers and email programs. Then you can easily scan the folder or label for the deals that fit your travel plans.
