It’s the first thing I do when the idea of a trip takes root, even if my travel dates or location are still up in the air.   Case in point: My longtime fellow Gen X travel buddy, Konnie Gurung, recently mentioned that she was about to start stalking airlines to find a low fare to Chicago. And really, who doesn’t want a low fare? Especially if you’re on a [fixed budget](https://www.aarp.org/money/personal-finance/retirement-budget-tips/ "how to stick to your retirement budget"), as many older adults are. _Set a fare alert_, I insisted. Again. It takes minutes, and then the stalking is done for you — a major time- and stress-saver. You receive an email updating you on price changes. Some even advise when it’s time to buy.  There are numerous platforms where you can set fare alerts, including: - Travel credit card providers - So-called OTAs (online travel agencies) such as Expedia, Hotwire and Priceline (if you sign up for its free VIP program) - Flight search engines like Google Flights, Skyscanner and Hopper, which allow you to book flights directly with airlines (and thus retain direct-booking protections).  The pros know. Patti Morrow, who writes about boomer travel on the website [Luggage and Lipstick](https://luggageandlipstick.com/ "visit the website"), says fare alerts are one of her top tactics for [finding cheap flights](https://www.aarp.org/travel/travel-tips/cheap-flights-tips/ "tips for finding cheap flights"). “It’s a good way to find out if the prices have dropped without being on the airline website every day,” says Morrow. Kyle Potter, executive editor at [Thrifty Traveler](https://thriftytraveler.com/ "visit the website"), likes to set an alert _after_ purchasing a flight. “Let’s say you book a $500 flight and you’re like, ‘Well, this is OK, but I wish it was better,’ ” he says. “You set a Google Flights price alert, and then you get an email that says, ‘Oh, this dropped to $400.’ You’re not stuck, so long as you didn’t book the cheapest Basic Economy fare \[which typically limits changes and cancellations\].… You could rebook that flight and then pocket that $100 difference.” Personally, I feel sufficiently backed up when I set the alert through my travel credit card provider’s booking portal. It tells me when to buy and includes price-drop protection. This means it automatically refunds the price difference of up to $50 in the form of a travel credit if the fare drops lower within 10 days. It’s happened before, and it’s a nice surprise.   As my conversation with my friend illustrates, knowing it’s helpful and easy to do, and actually doing it, are two different things. Here’s a simple airfare price alert how-to, designed to hit the “easy” part home. I’ll illustrate with Google Flights, an accessible favorite among the pros I speak with regularly. Most of the others follow a similar format. ![](https://cdn.aarp.net/etc/uxdia/images/uxdia-spinner.svg) ![a laptop with google flights on the screen](https://aarp.widen.net/content/sge6lmhiw6/jpeg/travel-109408-step1.jpg?crop=true&anchor=0,0&q=80&color=ffffffff&u=n1ks7w&w=1140&h=655 "Cheap Airfare Trick") Step One: Navigate to Google Flights.

AARP (Getty Images, Google) 5\. Scroll down to Track Prices. Toggle the X to the right for either the dates you plugged in or “any dates,” if you have flexibility. 6\. Congrats — your fare alert is set! You’ll receive regular email updates about fare changes. You can cancel the emails at any time.  For what it’s worth, Gurung set the alert, booked the cheap flight and is motivated to do it again. Honestly, it’s so easy.
