How to Set Price Alert and Save on Cheap Flights

What is Trip.com Price Alert?

Create price alert

Trip.com Price Alert is a free, global feature (app/desktop) that automates flight fare tracking for your chosen routes, dates, and cabin class. It eliminates constant manual checks by sending instant notifications when prices drop to your target budget.

How to Set Price Alerts on Trip.com

The Price Alerts setup process is similar for the Trip.com mobile app and desktop website. No membership or account upgrade is required (a free Trip.com account is all you need).

Step 1: Access the Flights section

Open the Trip.com app or go to the official Trip.com desktop site. Log in to your free account, then click/tap the Flights tab (a prominent icon/button on the homepage, top navigation bar for desktop).

Scroll down slightly—you’ll find the Price Alert button directly below the flight search bar (where you normally enter departure/destination dates). It’s a highlighted button to ensure easy access.

Step 2: Enter your flight details

On the Price Alert setup page, fill in your trip information (all fields are optional to customize, but the more specific, the more accurate the alerts):

• Departure city/airport and destination city/airport
• Travel type: One-way or Round-trip (add return dates if round-trip)
• Exact travel dates (you can set alerts for multiple date ranges for the same route)
• Cabin class preference (economy, business, first—defaults to economy)

Step 3: Set your target price range

Use the interactive price slider to adjust your budget (the slider shows the current average fare for your route as a reference). As you move the slider, the color-coded success rate indicator (red/yellow/green) updates in real time—use this to balance your budget and your chance of getting a low fare.

Step 4: Choose your notification method, Then Confirm

Select how you want to receive price drop alerts (you can select both for maximum coverage):

• App Push Notifications: Instant alerts to your phone (enable Trip.com push permissions in your device settings first)
• Email Notifications: Alerts sent to the email linked to your Trip.com account (useful if you don’t have the app open)

Click/tap the Confirm or Turn On Alert button to finalize your setup. You can view, edit, or cancel all your active Price Alerts at any time in your Trip.com Personal Center (under the Flights > Price Alerts tab).

Pro Tip: Set 2-3 price alerts for the same route (e.g., a "budget" green alert, a "stretch" yellow alert) to cover different fare scenarios.

How to Predict Flight Price Drops on Trip.com

Trip.com gives you real-time, free tools to predict fare drops. Combine these platform-specific cues with basic global airline trends, and you’ll know exactly when to wait for a drop (or book fast to avoid a hike).

1. Check the Price Trend Graph: The 7/14/30-day graph (flight search page) is the most reliable cue—if it shows a steady gradual drop, hold off and keep your Price Alert active. If it shows a rise, book immediately.
2. Look for Price Drop Tags: Trip.com labels flights with real-time tags (e.g., Limited-Time Price Drop, Today Only Special, Member Exclusive Fare)—these mean fares are below the 7-day average; book fast (seats are limited).
3. Act on Pre-Notifications: The Trip.com app sends minor fare drop pre-alerts (e.g., Fare down 8%—almost at your target!)—this is a clear sign a full drop is coming in 1–3 days.
4. Follow Global Promo Announcements: Trip.com posts global sales (airline anniversary deals, Black Friday, seasonal sales) on its homepage banner and sends push/email alerts 1–3 days early. Set a Price Alert for the sale window to lock in the lowest fares.
5. Book for Off-Seasons: Flight prices drop globally when your destination is in its off-season (low tourist demand). Trip.com’s flight search page flags a destination’s season status—use this to time your booking.
6. Watch for Low Inventory Warnings: If Trip.com shows Few seats left or Limited inventory, fares will rise soon (airlines hike prices for scarce seats). Book immediately—no drop is coming.

The Cheapest Time to Book Flights on Trip.com

Fare pricing on Trip.com mirrors global airline supply-and-demand rules—these universal booking times work for all routes and are based on real-time airline inventory updates.

Best Booking Windows on Trip.com

• Regional short-haul: Book 1–2 months in advance.
• Last-minute (same/next day): Check Trip.com at midnight–2 AM local time—airlines dump unsold seats at steep discounts to fill flights, and Trip.com updates these fares instantly.

Trip.com Cheapest Days to Book & Travel

• Book: Tuesday (midnight–8 AM local time)—airlines adjust fares on Monday evenings, and Trip.com posts these drops overnight; Tuesday mornings have the lowest global fares. Avoid booking on Mondays/Fridays (business travel demand drives prices up).

Trip.com Shoulder Season = Biggest Global Savings

Book flights for a destination’s shoulder season (the period between peak and off-season) for the lowest fares on Trip.com. Shoulder seasons have low tourist demand, so airlines cut fares to fill flights—Trip.com often adds seasonal promo discounts on top of these airline fares for global users.
