How to set up a flight price alert
Setting one up takes about a minute and needs no account. You give a route and the fare you would pay; we re-read the price every 15 minutes and write when a ticket reaches it. Walked through below on London — Bangkok.
Free. One click to stop, from any email.
Enter the route
Type the departure and destination cities and pick them from the dropdown. The dropdown matters: that is where the airport code comes from, and a city typed but not picked leaves us without one. Any pair with flights between them works, London — Bangkok as much as Auckland — Buenos Aires.
Dates are optional here. Leave them empty if the trip is still an idea rather than a plan.
See whether today is expensive
Press Track price and the route page opens with live fares: the cheapest option in each of the next three months, a day-by-day trend, and the actual ticket with flight numbers and times. Set a date and the page also says where that day sits against those months, whether it is a good price, below average, or above what the route usually costs.
That is a fact about the current spread, not a forecast. You can book from there straight away; the link goes to the search partner, since we do not sell tickets.
Name your price
Press Set up an alert. The price field arrives pre-filled with 20% off the cheapest fare currently visible on the route, so the starting number comes from real prices rather than out of the air. Change it to whatever you would actually pay. Alerts arrive in the currency shown next to the field.
Describe the trip
Five shapes cover almost every plan.
No dates — “whenever, as long as it is cheap”
Leave the dates empty and we check every one-way departure in the coming month, which is as far ahead as fares are currently held for watching. Any of those days that drops to your price is sent to you. Best for a holiday you can move around a good fare.
Exact date — “I fly on March 12”
Set the same day as departure and we watch only it, with no other dates in the way. If a nearby day turns out noticeably cheaper, that arrives as a separate note, at most once every five days, and it is a suggestion: your alert stays as you set it.
Exact-date alerts also get one reminder as the flight approaches, so a date you set months ago does not quietly pass by.
Round trip — priced as one ticket
Switch the ticket type and your price is compared against the whole there-and-back fare. Two cheap one-way flights often never exist on the same booking, and adding them up gives a number nobody can actually pay. Round-trip watching runs over departures in the coming week.
Trip length — “two weeks, dates flexible”
For a round trip without exact dates, give the length instead: up to a week, one to two weeks, two to three, or your own range within 2 to 21 days. We go through the departure and return combinations ourselves. Without that window the cheapest option is almost always a two-day hop, which is not the trip you meant.
Nonstop only
With the filter on, connecting flights disappear everywhere, including the cheaper-nearby notes. On some routes there are no nonstop flights at all; the alert stays valid and waits for one to appear and drop.
Choose where alerts go
Email is the main channel. Enter an address and a six-digit code comes to confirm it is yours. The code is good for 15 minutes and the message sometimes lands in spam. Once confirmed, the address is remembered in this browser, so the next alert needs no code.
Browser push works as the backup: the browser asks permission once and notifications arrive even with the site closed. Channels are per route, so work trips can go to the inbox and holidays to a push.
What arrives
Up to six of the cheapest matching options, one per departure date, so it reads as real choices instead of the same day six times. Each line has the date, the price, whether it is nonstop, and a link that opens that exact fare.
One alert per route per day at most. A departure date you already heard about comes back only if its fare drops another 15%, and not within two days of the last message.
Changing or turning off an alert
Everything lives on the alerts page: routes, prices, dates. Parameters can be edited, an alert renewed for another year, or switched off. Every email carries a one-click unsubscribe link, with no “log in to your account” in the way.
An alert lives a year from the day you create it, and a reminder goes out before it expires.
How often we look
Fares on watched routes are re-read every 15 minutes, around the clock, and a matching one is sent within about three minutes of appearing. That is the entire reason the service exists: a genuinely cheap ticket can live a couple of hours, and checking by hand twice a day misses it.
Prices come from our flight search partner and move through the day. We show what is on sale now and write when it drops. Buying still happens on the airline or agency site.
