You can get notified when flight prices drop by setting up price alerts on tracking tools before booking, as well as by using Going's Price Drop to keep watching the fare after you've already booked. Whether you're planning a dream vacation or a quick weekend getaway, tracking flight deals shouldn't feel like a full-time job. With just a few simple steps, you can sit back, relax, and let automated alerts do all the heavy lifting for you.

Key takeaways

  • Pre-booking price alerts notify you when fares drop before you buy, but they often stop tracking the moment you purchase a ticket.
  • If a flight price drops within 24 hours of booking, the US Department of Transportation's 24-hour rule allows you to cancel or change your ticket for free on flights to, from, or within the US.
  • After 24 hours, whether you can get a credit or cash refund depends on the airline and fare class. Basic economy fares are usually nonrefundable and non-changeable.
  • Post-booking monitoring tools like Going's Price Drop fill the gap by watching your booked fare and alerting you if it drops enough to make rebooking worthwhile.
  • Price alerts tell you when a fare moves, but they can’t predict future drops, so pairing them with post-booking monitoring gives you full coverage.

How to set up flight price alerts before you book

Setting up price alerts before purchasing a ticket is the best way to monitor airfare trends and catch low prices. You can toggle price tracking on tools like search engine price trackers or generic meta-search engines to receive email or push notifications when a fare changes.

What price alerts can (and can't) do before booking

Pre-booking price alerts notify you when fares fluctuate, but they cannot predict future drops or tell you with certainty whether you're getting the lowest price before departure. Most importantly, virtually all pre-booking price trackers stop monitoring your itinerary the moment you purchase your ticket.

The gap nobody talks about: what happens after you book

Once you buy a ticket, standard flight search engines and tracking tools stop watching your fare. If the price drops after your purchase, you are typically on your own to notice the change and request a credit or refund.

Can you get a refund if the price drops after booking?

It depends on when the price drops. If you catch it within 24 hours of booking, the US Department of Transportation's 24-hour rule requires airlines to let you cancel for a full refund on any flight that starts or ends in the US, as long as you booked at least seven days before departure. Rebook at the lower fare first, then cancel the original so you're never left without a seat. 

After that window, it comes down to your airline and fare type. Most standard economy fares or higher let you rebook at the lower price and take the difference as a travel credit, while basic economy fares usually can't be changed at all. 

Basically, if you spot a drop within a day of booking, book the new, lower fare and cancel the original within the 24-hour window. The common mistake is assuming you're stuck with what you paid and never checking.

If you've already booked your flight, Going's Price Drop can keep watching the fare for you. Set it up in just a few clicks to monitor your itinerary to ensure you never miss out on post-purchase savings.

Comparing your options: pre-booking tools vs. post-booking monitoring

Here's how the two halves of price tracking compare.

The two work at different stages, and most travelers only use the first half.

Pre-booking price trackersGoing's Price Drop
  • Watch a route or search and notify you by email or push notification when the fare changes
  • Work before you book, while you're deciding
  • Stop the moment you buy the ticket
  • Best for timing your purchase
  • Watches the fare on a flight you already booked and alerts you only when it drops enough to make rebooking worth it
  • Works after you've purchased
  • Keeps watching until your trip
  • Best for recovering the difference after booking

How Going's Price Drop watches your fare after you book

Stop postponing your purchase just because you're afraid the price might drop. Instead, keep receiving alerts after you book so you don't miss any savings. Price Drop watches the fare on a flight you've already booked and pings you only when it falls enough to make rebooking worth it. Here's how it works:

  1. Add your booked flight, and Price Drop starts tracking the itinerary.
  2. We watch the fare for you, so you don't have to check every day.
  3. If it drops enough to matter, you get an alert with the new price and the steps to rebook and claim the difference.

Frequently asked questions

Can I get airfare alerts when the price drops?
Yes. Flight-tracking tools let you set price alerts that notify you by email or push when a fare falls. Set them up before you book to time your purchase, and use Going's Price Drop to keep watching the fare after you've booked.
Can you get notifications for flight price changes?
Yes. Most flight-search platforms let you toggle on price tracking and send a notification when the fare moves. Just know the difference between a price change (any movement) and a price drop (a meaningful decrease). Most tools alert you to significant changes, not every dollar. See the pre-booking section above for how to set this up.
Is there an app that tells you when flight prices drop?
Yes. Apps exist to you send price-drop notifications for flights you're watching. For flights you've already booked, the Going app's Price Drop feature monitors the fare after purchase and alerts you when it drops enough to rebook.
How do I know if flight prices will go back down?
You can't know for sure. Nobody predicts fare movements with certainty. Alerts notify you of changes, but they don't forecast them. What you can do is track historical trends and set alerts.
What should I do if the price drops after I book?
If you're within 24 hours of booking, cancel and rebook at the lower fare for free under the DOT 24-hour rule. After that, check whether your airline lets you rebook for a travel credit. Basic economy usually can't be changed. Going's Price Drop can alert you when the fare drops enough to justify rebooking after fees.
