The Los Angeles International Airport (LAX) features several terminals that cater to numerous airlines, including Sun Country Airlines. As of my last knowledge update, Sun Country Airlines operates out of Terminal 5 at LAX.

When flying with LAX Airport Sun Country Terminal, you can expect a variety of amenities and services within Terminal 5 to enhance your travel experience. Upon arriving at the airport, it's recommended to allow ample time for check-in, security procedures, and potential navigation within the terminal.

Once inside Terminal 5, you'll find check-in counters where you can obtain your boarding pass and check any baggage if necessary. Many airlines, including Sun Country Airlines, offer self-service kiosks that allow passengers to check in and print their boarding passes for added convenience. 

After completing the check-in process, proceed to the designated security screening area. LAX is known for its thorough security procedures, so it's important to allow enough time to navigate through this process. The Transportation Security Administration (TSA) oversees security at LAX, and it's advisable to review their guidelines regarding prohibited items and security checkpoint protocols to ensure a smooth experience.

As you explore Terminal 5, you'll find a range of dining options, shops, and services to accommodate your pre-flight needs. Whether you're looking for a quick bite to eat, a last-minute travel necessity, or a moment of relaxation before your flight, Terminal 5 provides various amenities to suit diverse passenger preferences.

In addition to passenger services, Terminal 5 also includes essential facilities such as restrooms, seating areas, and information desks to assist travellers with any inquiries or concerns they may have.

For those waiting to board their flights, there are designated gate areas where you can relax before your departure. It's important to pay attention to announcements and flight information displays for updates on boarding times and gate assignments.

By providing these details, I aim to ensure that you have a comprehensive understanding of what to expect when flying with Sun Country Airlines from Terminal 5 at LAX. However, I recommend verifying this information with up-to-date sources or directly contacting the airline or the airport for the latest terminal details and any potential changes.
