How to Book a 2-in-1 Flight Deal

A 2-in-1 (or multi-city) flight creates an extended stay in another city in addition to your final destination—including the flight in between those two cities—all for one price on one itinerary. Here’s how to book one from a Going deal.

Step 1: Click the booking button in the deal email and find your travel dates

Every deal email includes a direct link that’s pre-set with all the filters needed to get the fares we’ve found to appear in the search results.

Explore available dates until you find an itinerary you like. Note: You may need to customize your search details, such as dates, trip duration, number of travelers, etc.

Step 2: Switch your flight type to “multi-city”

Look for a dropdown menu where you can select the type of trip and select multi-city flights (instead of round trip or one way).

Here’s what this looks like in Google Flights:

Step 3: Add in additional city

Once you’ve changed your search to multi-city mode, add in any additional stop(s) you want to make, and the travel dates.

If the order you visit each city doesn’t matter to you, try searching both ways to see if you can get a lower price.

choosing cities and dates in google flights.

Step 4: Book via the airline or an online travel agency

Going doesn’t sell flights; all flights must be booked directly through the airline or an online travel agency.

Online travel agencies often have the lowest available prices for our deals. When this occurs, we’ll call it out in the Booking Instructions section of the email. When the price is similar, we recommend booking directly with the airline.

Not only does this give you more flexibility (you can generally cancel or change your flight within 24 hours), it’s also typically easier to resolve any issues when you deal directly with the airline vs a third party.

For detailed instructions on how to use the most common online travel agencies or flight search engines, check out these guides, or read our guide to online travel agencies.

Can’t find the fare quoted in the deal alert email?

If you’ve followed the instructions above (use that booking button!) and still can’t find the deal, double check the dates and route (departure and destination airports) in the deal email to make sure the dates you’re searching for are listed.

For a 2-in-1 deal, check the booking instructions for additional notes; sometimes the deal only works when the cities are visited in a specific order. If you still can’t find the deal, it’s most likely no longer available.

Founder & Chief Flight Expert

Scott Keyes is the Founder and Chief Flight Expert of Going (formerly Scott’s Cheap Flights), an app for flight deal alerts. He launched the service after spotting a $130 roundtrip fare from New York to Milan in 2013 and turned that discovery into a hobby of alerting friends to exceptional flight deals. Within two years, he formalized the email list into a business, culminating in the 2015 founding of the email service that has grown to serve more than 2 million members, sending them flight alerts for cheap flight tickets and mistake fares to destinations worldwide.

With a background in journalism and an education from Stanford University, Keyes spent years investigating airfare pricing, airline yield management, and consumer booking behavior. He worked with the Going team to build a mobile app, launched in 2024, that scans thousands of routes and publishes curated low‑fare alerts. The community has saved members over $1 billion in airfare in ten years, according to Mercury. His insights and story have been featured in The Washington Post, CNBC, Yahoo, Fortune, and more, where he has shared data-driven strategies on airline pricing patterns and booking optimization.

Alongside his role at Going, Keyes authored the book Take More Vacations: How to Search Better, Book Cheaper, and Travel the World (Harper Wave, 2021), which presents his methodology and encourages travelers to prioritize price‑first trips rather than destination‑first. Through speaking engagements and media commentary, he is widely cited as an authority on how to secure mistake fares, fare drops, and unadvertised deals.

Keyes is based in Portland, Oregon. His work bridges data‑driven airfare analytics with travel psychology, and he is committed to making global travel more affordable and accessible.
