Sun Country Airlines: Do They Have an App?

Last Updated on July 25, 2026 by Daniel Globe

Yes, Sun Country Airlines has an official mobile app for iPhone and Android. The app focuses on the tasks travelers are most likely to need before and during a trip, including booking flights, managing reservations, checking in, accessing a boarding pass, adding bags or seats, and checking flight status.

Why the Sun Country Airlines App Is Useful

Sun Country Airlines was founded in 1982 and is based in Minneapolis, Minnesota. It operates as a hybrid low-cost carrier with scheduled passenger, charter, and cargo operations. Its passenger network includes destinations across the United States, Mexico, Central America, Canada, and the Caribbean.

For travelers, the app’s main value is that it places common booking and day-of-travel tools in one location. Instead of searching through confirmation emails or opening several browser pages, a passenger can use the app to find a trip, check its status, manage selected extras, and retrieve a boarding pass.

The app is most useful during the 24 hours before departure. That is when check-in becomes available and travelers are more likely to need their boarding pass, seat information, bag selections, departure time, or gate details.

Sun Country Airlines App Features

The official Sun Country mobile-app page and current app-store listings identify the following core features:

• Book flights: Search for destinations and dates, review available flights, and complete a new booking.
• Manage trips: View upcoming reservations and access available options for changing or preparing a trip.
• Add bags: Purchase eligible bag options through the booking or trip-management flow.
• Select seats: Review available seats and purchase a seat selection when the option is available.
• Check in: Complete mobile check-in between one and 24 hours before the scheduled departure time.
• Access a boarding pass: Display the mobile boarding pass after successful check-in.
• Save to Apple Wallet: The iPhone app supports saving an eligible boarding pass to Apple Wallet.
• Check flight status: View current information for your own trip or another Sun Country flight.
• Access your profile: Sign in to Sun Country Rewards, view account information, check available points, or join the program.
• Use supported payment options: Recent iPhone updates added Apple Pay for eligible purchases such as bags, seats, or priority boarding.

Features You Should Not Assume Are Guaranteed

The official feature descriptions do not promise that every delay, cancellation, or gate change will generate a push notification. They also do not establish a permanent program of app-only discounts.

Use the app to check current flight information, but continue monitoring the email address and mobile number attached to the reservation. Airport departure screens and gate announcements remain important on the day of travel.

How to Download and Use the Sun Country Airlines App

1. Open the correct app store. Use the Apple App Store on an iPhone or Google Play on an Android device.
2. Search for “Sun Country Airlines.” Avoid similarly named travel tools or unofficial apps.
3. Verify the developer. The official listing identifies the developer as Sun Country, Inc. or Sun Country Airlines.
4. Install the app. The app itself is free, although mobile-data charges and purchases made through the app may still apply.
5. Open the app and review permissions. Allow only the notifications, location access, or other permissions you are comfortable granting.
6. Sign in or retrieve your trip. A Sun Country Rewards login can make account and trip information easier to access. Keep your confirmation email and reservation details available in case the app asks you to locate a booking.
7. Review the trip. Confirm passenger names, dates, departure airport, destination, bags, and seat selections.

Do You Need a Sun Country Rewards Account?

A Rewards account is useful because it can display profile information, available points, and trips associated with the account. Recent app updates have also made it possible to join Sun Country Rewards from the app.

However, do not assume that joining the loyalty program is required for every travel function. Passengers should keep their booking confirmation and reservation details available when retrieving or managing a trip.

How to Check In and Get a Mobile Boarding Pass

Sun Country states that app check-in is available between one and 24 hours before the scheduled departure time.

1. Open the app and locate the correct trip.
2. Select the check-in option after the check-in window opens.
3. Confirm the passengers who are checking in.
4. Review the required travel and hazardous-material notices.
5. Add or review bags, seats, or eligible priority options if needed.
6. Complete check-in and open the boarding pass.
7. On an iPhone, use the Apple Wallet option when it is offered.

If you have a valid mobile boarding pass and are not checking a bag, you may be able to proceed directly to security. Follow the instructions for your departure airport and allow time for any required document or identification checks.

Benefits of Using the Sun Country Airlines App

Faster Access to Travel Details

The app keeps upcoming trips, flight status, and boarding-pass access in one place. That can reduce the time spent searching through emails at the airport.

Mobile Check-In

Checking in before reaching the airport can save time, especially when you have no checked luggage and receive a valid mobile boarding pass.

Trip Management

The published feature set allows travelers to add bags, review or choose seats, and adjust eligible trip details through the app’s management flow.

Flight-Status Checks

You can use the app to review current flight information for your trip or check another Sun Country flight. This is useful when meeting an arriving passenger or monitoring a connection.

Rewards and Profile Access

Rewards members can access account information and view available points. Travelers who have not joined can use the app’s signup option when available.

Less Dependence on Paper

A mobile boarding pass can reduce the need to print documents. You should still carry required identification and any destination-specific travel documents.

The app is most valuable as a day-of-travel tool, but it works best when paired with email, SMS updates, airport displays, and access to SunCountry.com.

Customer Reviews and Feedback on the Sun Country App

Customer feedback is mixed. When checked on July 26, 2026, the U.S. Apple App Store showed a 2.6 out of 5 rating from 223 ratings. Google Play showed approximately 3.0 out of 5 and more than 100,000 downloads. These figures can change as new ratings and app updates are published.

Positive feedback commonly focuses on having check-in, trip information, and boarding-pass access in one app. Some travelers also appreciate Apple Wallet support and the ability to manage bags or seats without opening a separate browser page.

Negative reviews have mentioned booking pages that fail to load, incorrect or delayed trip information, unexpected logouts, offline messages, and problems completing check-in. These reports do not affect every user, but the current store ratings show that reliability has been inconsistent for some travelers.

App-store reviews are anecdotal rather than controlled testing. Device model, operating-system version, connection quality, reservation type, app version, and temporary service problems can all affect the experience.

What to Do If the Sun Country App Is Not Working

1. Confirm your connection. Switch between Wi-Fi and cellular data to determine whether the problem is network-related.
2. Update the app. Install the latest version from the official app store.
3. Update the phone. An outdated operating system can cause compatibility problems.
4. Close and reopen the app. Fully close it rather than leaving it suspended in the background.
5. Refresh the trip. Pull down to refresh where that function is available, or reopen the trip from the home screen.
6. Sign out and sign back in. Do this only when you know your login details or have access to the account’s password-recovery method.
7. Check the reservation details. Confirm that the name, email address, confirmation information, and travel date match the booking.
8. Use the website instead. Try the official Sun Country check-in page or Manage Trip page.
9. Use another communication channel. Review your confirmation email, optional SMS alerts, and the flight-status information on SunCountry.com.
10. Allow time for airport assistance. If online check-in remains unavailable, arrive early enough to resolve the issue with an airport agent.

Privacy and Data Permissions

The Apple and Google listings disclose that the app may handle information such as contact details, identifiers, usage data, diagnostics, location, and payment information, depending on the platform and features used.

Review the permissions shown during installation and in your phone’s settings. Location access may help certain functions, but travelers should grant only the access they consider necessary. Sun Country’s current privacy terms are available through the app-store listings and the airline’s privacy policy.

Comparing Sun Country’s App With Other Airline Apps

Compared with the apps of larger network carriers such as Delta or American Airlines, Sun Country’s published feature set is narrower and more focused on basic booking and day-of-travel tasks.

That simplicity can be an advantage for a traveler who mainly wants to:

• Find or book a Sun Country flight
• Manage an existing trip
• Add a bag or seat
• Check in
• Display a boarding pass
• Check flight status
• View Rewards information

Larger airline apps may include a wider range of operational tools, but the number of features is not the only measure of quality. Reliability, accurate trip data, clear navigation, and easy access to a boarding pass are more important during travel.

Because Sun Country’s current store ratings are mixed, travelers should install and test the app before the day of departure rather than relying on it for the first time at the airport.

Is the Sun Country Airlines App Worth Using?

Yes, the Sun Country Airlines app is worth installing when you have an upcoming Sun Country trip. Its verified features cover the most important tasks: booking, trip management, bags, seats, check-in, boarding-pass access, flight status, and profile information.

However, it should be treated as one travel tool rather than the only source of critical information. Current user ratings show that some travelers have experienced technical problems. Keep your confirmation email, monitor Sun Country messages, check airport displays, and know how to reach the airline’s website if the app does not load.

The app is free, so testing it before departure has little downside. Open your reservation, confirm that the trip displays correctly, and make sure you know where the check-in and boarding-pass controls are before the 24-hour check-in window begins.

If you are traveling internationally, keeping your devices charged may require the correct plug adapter at your destination. This guide to universal travel adapters for international trips explains several common options.
