How It Works – 3 Easy Steps!


Create an Account

Sign up for a free or premium account using an email address and password. You can upgrade to premium (Sky Arb Pro) at any time or cancel your subscription with the click of a button. Select from 24 US departure airports for receiving alerts (see map below).


Receive Email Alerts

Begin receiving email alerts on discounted international flights by setting your US departure airport preference (e.g. LAX, NYC, MIA) and monitoring your inbox for our weekly emails. Each email will have multiple location-specific alerts for the latest discounted airfare.


Save on Your Next Flight

When you see an alert with an excellent price that you want to book, use one of the provided booking services such as Momondo, Google Flights, Skyscanner, or Kayak to purchase a ticket. We provide all of the links in our email alerts to make booking simple. Sky Arb is not able to book flights, we instead alert you when there's great pricing.

How Sky Arb is Different

Sky Arb is the first independent email alert service that uses algorithmic searching and big data to identify discounted airfare for thousands of destinations worldwide. Our simple alert structure, broad search capabilities, and competitive pricing helps users get the most out of their free or premium Sky Arb subscription.

Simple Alert Structure

We combine several flight alerts into a single email and send bulk messages approximately once per week. This organizes our alert communications and keeps subscribers’ inboxes uncluttered.

Broad Search Capabilities

We use algorithms to search over 15,000 flight routes departing from the United States each day. The breadth of our searching helps us find the lowest airfares from the best airlines.

Competitive Pricing

Our premium Sky Arb Pro subscription is priced competitively and our free subscription offers excellent utility at zero cost. We aim to always offer travelers a strong value.


We are independent of airlines and are not affiliated with any travel service providers or search engines. This helps us find the lowest prices, no strings attached.


We send email alerts that present meaningful savings and that can be used quickly and reliably. We are always searching so that you are always saving on flights.


We take your privacy seriously. We do not store or sell your personal information. Unsubscribing is just as easy as signing up; that’s the way it should be.
