Sending real-time alerts using IFTTT

To have a chance at getting these cheap fares, we're going to need to know in nearly real time when they happen. To accomplish this, we'll use a service called If This Then That (IFTTT). This free service allows you to connect a huge number of services with a series of triggers and actions. Want to save as many pictures as you like on Instagram to your iPhone photos? Want to get an email every time a particular person tweets? Want your Facebook updates posted to Twitter? IFTTT can do all of this. Go through the following steps:

1. The first step is to sign up for an account at http://www.ifttt.com.
2. Once you've done that, you'll need to sign up for the Maker channel, https://ifttt.com/maker_webhooks, and the SMS channel, https://ifttt.com/sms.
3. Maker allows you to create IFTTT recipes by sending and receiving HTTP requests.
