Online check-in AeroLogic - https://www.check-in.site

As of my last training cut-off in September 2021, AeroLogic, a German cargo airline, doesn't provide passenger flights, so they wouldn't have an online check-in process for passengers.

AeroLogic is a joint venture between DHL Express and Lufthansa Cargo, providing air transport for cargo and freight only. It operates a fleet of Boeing 777F aircraft.

For airlines that do offer passenger services, online check-in typically involves visiting the airline's official website, finding the "online check-in" or similar section, entering your booking details, and following the on-screen instructions. This usually opens 24-48 hours before flight departure and closes a few hours before the flight.

Please note that the information could have changed post my training data in September 2021. For the most accurate and current information, always refer to the airline's official website or contact their customer service.
