How to Get a Flight Price Drop Alert by Email
There are a few ways to get a flight price drop alert by email: price tracking on Google Flights, a price alert from Kayak, Skyscanner or Hopper, a deal newsletter like Going or Secret Flying, the airline's own sale emails, or one sentence handed to MailMeWhen, which needs no account and no app.
Flight prices move several times a day, and the fare you saw on Tuesday is rarely the one you get on Friday. If your dates are fixed, the only way to catch a drop is to keep looking — and nobody wants to open five tabs every morning for a month.
Ways to get a flight price drop alert by email
A flight price drop alert in one sentence
Tell MailMeWhen the route, the dates or the month, and what counts as good news — 'below €120 return' or 'any drop from today's fare'. A real person reads the request and sets it up. Nothing arrives while the fare holds; when it drops, a short letter names the price seen and where, with a link so you can check it and book. The booking stays with you — MailMeWhen never buys anything on your behalf.
The first 7 days are free, with no payment details. After that it is $5/month for that one alert, and it stops by itself if you don't subscribe. Reply once to stop, or to change the dates.
Good to know about flight price drop alerts
Decide what 'the price' is before you set anything. Fares differ between sites and between what's included — a bag, a seat, the return leg — so a drop on one site can be a different fare rather than a cheaper one. Name the total you care about, luggage included, and compare that.
Flexibility is the real lever. If the dates or the airport can move, say so — 'any weekend in October', 'from either Paris airport' — because the cheapest fare is usually a day or two away from the one you first picked.
An alert is a trigger, not a ticket. Good fares last hours, sometimes minutes, so when the letter comes, book. No alert, this one included, holds a seat for you.
Try it — hand us this sentence:
Watch return flights from Amsterdam to Lisbon for October 8–15 and mail me if the fare drops below €120.
Common questions
How often is the fare checked, and how fast will I hear about a drop?
The checking is the part you hand over. Nothing arrives while the fare holds; a short letter comes when it drops below the line you set, or drops at all if that's what you asked for. Within 24 hours of your request one letter confirms the route, the dates and the fare it starts from — and if that route can't be watched, because some airline sites resist automated reading, that first letter says so instead of going quiet.
What if the flight price drops after I've already booked?
Usually nothing changes: most fares are non-refundable and the airline keeps the difference. A few airlines refund the gap or give a travel credit, and in some countries a booking can be cancelled free within a day of making it — so if you're inside that window and the drop is big, cancel and rebook. Read the fare rules before you count on either.
Can I watch flexible dates, or a whole month?
Yes. 'Any weekend in October', 'the cheapest week in November', 'from either Paris airport' — the sentence is the setting, and the wider it is, the more likely a good fare turns up. Google Flights' 'any dates' tracking does something similar for one route; here you can add the bag, the number of seats and the most you'll pay in the same sentence.
