Bet You Didn’t Know: Mistake Fares Exclusively for Your City or Airline

By Julian, author of Devil’s Advocate


Last week I wrote about some of the tools I use to quickly find and book mistake fares (see “Bet You Didn’t Know: A Toolkit for Chasing Mistake Fares). It was a popular post, but a number of folks mentioned that subscribing via text to every tweet from @TheFlightDeal and @FareDealAlert can mean getting a lot of daily texts, many of which might not be relevant.

Personally, I like receiving every deal those guys find, even if many of them don’t directly apply to me. Sometimes seeing a routing can give you ideas that you might not anticipate. For instance, I live in Los Angeles but travel to New York often enough that mistake fares from both the East and West Coasts, and even the middle of the country, can be potentially useful to me.

However, I realize not everyone is insane like me. Actually, I like to think that I’m insane in my own special way, but that’s probably part of my insanity. In any case, it’s certainly fair to ask if there’s a way to cull all the texts down a bit.

So with thanks and hat tips to several commenters from last week, including Carlos, Yihwan, and a guest, today we’ll cover exactly how to filter all those mistake fares so you can be alerted immediately to the deals only for your hometown, or a specific airline, or both.

First, do not panic!

The method I noted last week to turn on mobile notifications from Twitter is the simplest way to get informed of these deals. Today’s procedure is slightly more complicated, but far from difficult. Also, while this technique involves using an RSS feed, you do NOT need to setup or maintain an RSS reader of any sort. We’re only using the RSS feed as a source, so if you’re not an RSS expert, don’t worry, you don’t need to become one anytime soon.

What you will need is to sign up for a free service known as “If This Then That” (or IFTTT for short). You can find it at Signing up takes about 10 seconds and requires nothing more than a username, an e-mail address, and a password.

IFTTT is a great little tool that allows you to create what are technically known as “conditional statements.” A conditional statement is just what it sounds like — it’s a statement that if one action occurs, then another will occur as well. The most prominent conditional statement in my own life goes something like “if I continue to eat all this chili, then I will continue to get as fat as an elephant.”

In this case, we’re going to use IFTTT to set up a conditional statement using the RSS feeds from The Flight Deal and Fare Deal Alert. We’re going to tell IFTTT that if The Flight Deal posts a deal involving our hometown or airline, then send us a text.

Setting up IFTTT for a specific city or airline

Once you’ve signed up for IFTTT, you’ll want to click on “My Recipes.” Recipes are what IFTTT calls their conditional statements. Click the blue “Create a Recipe” button on the right to start building your Flight Deal or Fare Deal Alert recipe.

On the page that follows, when you click on the blue word “this” in the words “if this then that” IFTTT will ask you to choose a “trigger.” A trigger is just the “if” part of your conditional statement.

There’s about a gazillion possible triggers, but the one we’re looking for is the RSS feed, which is labeled with the standard internet Feed Icon. If you don’t know what that looks like, it’s an orange square with white radio waves and labeled “Feed.”

Click on the Feed Icon and IFTTT will ask if you want to be alerted for every new feed item, or if you want to filter what you receive. Since we’re trying to restrict our texts, we want to click on the “New feed item matches” box.

Here’s where we get to decide what we want to see. If you live in New York and only want fare deals from there, you can enter “New York” into the keyword box. If you have Diamond status on Delta and only want to fly Delta, enter “Delta.” You can put anything you want in the keyword box, and IFTTT will only alert you when fares are posted with that keyword.

But what about both?

Of course, some of us want to filter our alerts even further, perhaps by both city and airline at the same time. Unfortunately IFTTT doesn’t support search operators or complex search terms (such as “New York AND Delta”) but there’s a way around this. Luckily both The Flight Deal and Fare Deal Alert provide separate RSS feeds by city, which we can use to our advantage.

If we want all the Delta fares from any city posted on The Flight Deal, all we have to do is type “Delta” in the keyword box and add “” (without the quotes) in the Feed URL box. Note that for both The Flight Deal and Fare Deal Alert, you can see their webpages in an RSS feed by simply adding the word /feed/ to the end of the URL.

But if we only want to see Delta flights to or from New York, we’ll keep Delta in the keyword box but change the URL to only use The Flight Deal’s NYC feed…

It’s cut off in this screenshot, but the word “feed” is at the end of the Feed URL after the “nyc” part.

You can find all the various city feeds on The Flight Deal and Fare Deal Alert’s websites under the “Flight Deals” tab at the top left of their main pages. Just don’t forget to add /feed/ to the end of the URL when you enter it here on IFTTT.

Once you’re finished with your filtering and RSS choices, click the blue “Create Trigger” button and IFTTT will confirm your choices.

And now it’s time for Then.

The hardest work is done — the rest is easy. All we have to do is tell IFTTT how we want to be alerted when a fare post hits that matches our filters. In other words, the “then” portion of our recipe, which IFTTT calls “actions.”

Click on the blue word “then” in the main “if this then that” text and you’ll be given a list of options for actions. As I mentioned last week, my personal preference is to receive alerts by text, as I find that’s the fastest and easiest way to get them to my phone. But you can choose any way you want to be alerted — text, e-mail, iPhone or Android notification. Even a Facebook post, though I’m not sure how that would be useful here. Of course I believe Facebook is destroying the fabric of the universe, so I’m probably not the best person to ask on that one.

Whatever method you choose, just pick it from the Actions menu. Most of the choices are self explanatory, but for texts, you’ll want to choose the dark green “SMS” icon.

The very first time you choose an action, you may be prompted to “activate the channel.” This just means setting up your cell number or e-mail for use on IFTTT. The prompts are very easy to follow, so I won’t spell them all out here. For SMS texts, it’s the usual process of having IFTTT send you a text with a PIN to be certain you’re trying to set up your own cell phone and not someone else’s.

Once you’ve done that and selected “Send me an SMS,” you can customize the format of the text you’ll be receiving. Usually the default settings will be fine.

You can leave all these settings the way you find them.

Click on the blue “Create Action” button and you’ll be at the final step, which is confirming everything you’ve done on one screen…

All you have to do is click on that final blue “Create Recipe” button and you’re off and running!

If at any point you want to alter the settings on your recipe — either to filter a different airline or city or to change where you want the alerts sent — click the edit button (it looks like a pencil) on the main “My Recipes” page and you’ll be able to change anything you need. You can also create multiple recipes for different cities and airlines and have them all running at the same time.

The one danger if you’re filtering airfare alerts is that when a big mistake fare hits that doesn’t conform to your filters, you won’t get the message. For instance, if you had our example filter in place, you wouldn’t have gotten alerted about last week’s American Airlines mistake fare from Washington to Beijing because it wasn’t from New York and it wasn’t on Delta. But if you don’t live anywhere near Washington and don’t want to be bothered with a positioning flight, then you can safely use IFTTT to filter out anything that isn’t useful to you.

Did you know how to use IFTTT to filter mistake fares for your city or airline?

  1. Great how-to, I’ve read other posts about twitter and SMS and have my own yahoo pipes generating RSS feeds that I watch but having triggers that go right to SMS is very helpful and more useful to everyone who doesn’t use RSS…

  2. I’ve been kicking myself over and over for not checking my feeds or email the day of the Beijing mistake fare, made so much more painful as we’re about to spend miles for a flight into Beijing next week… This is great, thanks. It will at least help so I’m hopefully better prepared for the next one.

  3. thanks so much! I’d been thinking I should send Flight Deals to myself via SMS, but I just sent it up to just send Philly deals to me!

  4. I have made 3 mistake fares because of these techniques. Here are the recipes I use:

    Frequent Milers Quick Deals
    Trigger –> Feed URL –>

    The Flight Deal (replace philadelphia with your city)
    Trigger –> Feed URL –>

    Flyertalk Mileage Run Deals
    Trigger –> Feed URL –>

    Between these alerts and getting texts from Twitter feeds, I see a lot of stuff. Once you get used to all the messages, it becomes very easy to quickly scan and then delete or open.

    I actually saw the DCA-PEK via FMQD when it showed as expired but I got on the computer anyway and got one!

    Great article!

  5. Great post. Mind commenting how frequently are these particular feeds populated, and therefore sent to you via sms or email?

    I’ve only used IFTTT recently and that is for notification of PM on Reddit. Its pretty reliable, though for people who are not familiar, IFTTT notifications are not instant, it checks every few minutes for new items (10-15?).

    • The Flight Deal and Fare Deal Alert have a general guideline of only posting international fares they find for less than 6 cents per mile, so the frequency depends on how many fares they find that meet that criteria. Some days it’s a lot and other days it’s fewer, depending on what fares the airlines are putting out there at any given time. However, if you include all the cities they cover, I’d say those sites together usually have at least 10-20 deals a day on average, so that’s how many times the feeds are populated.

      You are correct to note that IFTTT can have a slight lag depending on what channel you’re using, but they state the maximum it would ever be is 15 minutes, so hopefully that’d be fast enough in a mistake fare situation.

  6. Great tip! However, I prefer using an Android notification over SMS.. I run a similar formula during the holidays to track a totally different event and found that I was running over my text message limits pretty quickly.

      • I’m an iPhone guy so I can’t speak to how the Android notification portion of IFTTT works, but using other options such as Android notifications would be a good way to avoid extra text messaging charges, especially if your cell phone plan is data-heavy and text-light.

    • If you’re using feeds from Flight Deal and Fare Deal Alert, I’d suggest city names like “New York” in order to capture deals from all the airports in any given area. Those sites are very consistent in labeling their posts with full city names. Other sources might be less consistent or use ITAT codes, so keep that in mind.

  7. No way – I was just thinking about how to do this a week ago when I signed up for IFTTT and then again last night as I was searching recipes to use for twitter posts. Thanks for the tips – this makes my job of figuring it all out by myself that much easier.

  8. Excellent post……you are in rarified air on this one……..I set this up last week from the posts you had forwarding from another blog and it is “working like a charm”……..before I was getting peppered 20 times a day with sales I didn’t want…….now I’m getting peppered 1-2 times a day with sales I don’t want………but I have faith that this system will eventually reap great benefits for me and my family……….and for that and what FM and staff do on a daily basis we ARE GRATEFUL………..just a wonderful addition to my daily routine……..

  9. I am a non-techie and found your directions easy to follow.
    I also last week followed your directions to follow the 2 fare alert sites and enable mobile notification.
    Should I now go back to those 2 twitter pages and disable mobile notification if I’ve now set up the IFTTT RSS feed? Thanks!

    • If you’re using the main feed via IFTTT and RSS and not filtering, then it’s the identical content as the mobile notifications via Twitter, so yes, you can disable the Twitter versions. Though keep in mind that if you are filtering via IFTTT, you’ll only see a portion of all the deals via those sites.

  10. Any idea how to set it up to only alert on genuine mistake fares?

    Also, theflightdeals twitter deals are posted every hour, on the hour, except for mistake deals.

  11. This is awesome! Thanks for sharing! It makes me think there’s gotta be a recipe you can then also set up for those big mistake fares in general … will have to think on this!

  12. I received a message from the IFTTT team that says the following:

    You have reached IFTTT’s monthly limit of 10 SMS messages.

    All of your Personal Recipes that send SMS messages are paused until Wednesday, April 01, 2015.

    Is there any way to change this limit? I got that many SMS messages in one day.

    • There are SMS limits on IFTTT but I didn’t think they were as low as 10 messages, unless they’ve been recently changed. However, if you’re hitting an SMS limit, just try using a different channel, such as e-mail, Android notifications, or iPhone notifications, and you should be able to get around the problem. [UPDATE: Apparently the limits were changed sometime in the last year (an unannounced devaluation!) so if you’re not filtering or you’re getting more than 10 SMS messages a month even with filtering, use another channel instead.]

  13. This is awesome. I had PushBullet, but never really implemented it, now I have and already got alerts over the weekend. Great use of technology and great post outside the lines a little bit from the usual stuff. I love it.

  14. Hmm this doesn’t seem to be working for me. Let’s see if someone can help:

    My recipe reads: If new feed item from, then send a notification

    And the notification is an Android notification. But I’ve had it on for the past two days, and I checked the site to see that new items have posted, but I have not received any Android notifications in the past two days. Anyone have any ideas?
