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

As of my last training cut-off in September 2021, Aero Contractors, a Nigerian-based airline, may offer online check-in services. The specifics for the online check-in process can vary widely among airlines and could change over time. However, the general process for online check-in for most airlines is as follows:

1. Visit the official website of the airline.

2. Look for an option labelled "Online Check-In", "Web Check-In", or similar. It can often be found in the main navigation menu or within a "Manage Your Booking" or "Passenger Services" section.

3. After selecting this option, you will typically be prompted to enter your booking reference or ticket number and your last name.

4. Follow the on-screen instructions to complete the check-in process. You may be given the option to choose your seat, and you may also be able to print out your boarding pass or have it sent to you via email.

Online check-in usually becomes available 24-48 hours before the scheduled flight departure time and often closes a few hours before the flight. The availability of online check-in can depend on factors such as the specific flight and the departure and arrival airports.

However, this information is based on my knowledge as of September 2021, and the actual process may have changed or differ slightly. Always refer to the most recent information provided by Aero Contractors on their official website or contact their customer service for assistance.
