Finding travel deals can be difficult. Here are some things to remember when you’re planning a summer getaway.

1. Fast action: When a deal goes up on Twitter or the site of an airline or hotel, they usually only last for a certain amount of time OR until the deal on those items is snatched up. For example, Jet Blue sometimes offers deals until 6 pm or until the 25 seats it’s offering have been bought. In order get the deal, you have to be on top of your deal game.

2. Dates: Often companies will allow a deal only for specific dates, which means that when you enter the dates you want to travel, you’re met with the normal price. Check for small print at the bottom of the page to see what the deal is. Be flexible with your dates to receive the best prices (hint: leave and return during mid-week).

3. Travel Agencies: Be wary of composite travel agencies and their offerings. Hotwire, for example, frequently has pop up style deals that present a much cheaper price than in actuality. Even when you sign up for email notifications, there’s often a chance that deceit is around the corner.
