Delta Air Lines offers a comprehensive check-in system designed to accommodate various passenger preferences. The airline's online check-in portal opens 24 hours before scheduled departure and can be accessed through Delta's official website or their highly-rated mobile application. During this process, travelers can confirm their flight details, select or modify seat assignments, purchase additional baggage allowance if needed, and obtain their boarding passes in digital or printable format. Delta's mobile boarding passes are particularly convenient as they can be saved directly to smartphone wallets for easy access throughout the journey.
At the airport, Delta provides multiple check-in alternatives to suit different needs. Full-service check-in counters staffed by Delta representatives typically open two hours before domestic flights and three hours before international departures. For passengers seeking a quicker option, self-service kiosks are available at most Delta-served airports, allowing travelers to check in, print boarding passes, and tag their own luggage without waiting in line. These kiosks are especially useful during busy travel periods when check-in lines may be longer than usual.
Delta enforces specific baggage check deadlines to ensure smooth operations. For domestic flights within the United States, checked baggage must be received at least 45 minutes before departure, while international flights require baggage to be checked at least 60 minutes prior to takeoff. The airline's Sky Priority service offers expedited check-in benefits for Delta Medallion members, premium cabin passengers, and eligible partner airline status holders, featuring dedicated check-in lanes and priority baggage handling. Delta also provides special assistance check-in areas for passengers requiring additional support, such as those traveling with young children or passengers with disabilities.
