recommended and efficient method is online check-in, which opens 48 hours before your scheduled flight departure and closes 1 hour before domestic flights and 2 hours before international flights. Passengers can complete online check-in through the official LATAM Airlines website or the LATAM mobile app. To begin, you just need to enter your booking reference and last name, then you can select your preferred seat, add any extra baggage if needed, and print or download your boarding pass to your phone. Using the digital boarding pass helps speed up the process at airport security and boarding gates. For those who prefer to check in at the airport, LATAM provides check-in counters that open about 3 hours before departure and close 1 hour before domestic flights and 2 hours before international flights. It’s important to arrive early, ideally at least 2 hours before domestic flights and 3 hours before international flights, to allow time for check-in, baggage drop-off, security checks, and reaching the gate comfortably. In addition, LATAM offers self-service kiosks at many airports, which provide a quick way to check in, print boarding passes, and print baggage tags without waiting in long lines. After using the kiosks, travelers with checked luggage can proceed to the dedicated bag-drop counters. These kiosks typically operate during airport working hours and close approximately 45 minutes before departure. LATAM also provides priority check-in counters for Business Class travelers, LATAM Pass elite members, and passengers who require special assistance. These priority counters help reduce wait times and offer a smoother check-in experience. For passengers flying on codeshare flights operated by partner airlines, check-in procedures may vary, so it’s best to confirm the check-in details with the operating carrier. Additionally, if your journey involves connecting flights, be sure to allow enough time between connections to complete any necessary check-in or baggage transfer processes. It is essential to adhere to LATAM Airlines’ check-in deadlines to avoid denied boarding or missed flights. Passengers should also ensure that all travel documents such as passports, visas, and health certifications meet destination requirements before check-in. To make your travel experience hassle-free, always prepare your documents and baggage in advance and consider completing online check-in as soon as it opens. In conclusion, LATAM Airlines offers flexible check-in options starting 48 hours before departure online, with airport counters opening 3 hours prior and closing between 1 to 2 hours before flights depending on the route. Using online or mobile check-in is highly encouraged for faster airport processing, while airport counters and kiosks provide assistance for passengers who prefer in-person service or have checked baggage.
