There are many reasons you cannot check in online with British Airways. The most common reason is that you might be facing a technical problem, such as glitches on the website, or there is work going on the server after some time; you can check in again.
The other reason can be the flight has been overbooked. In some cases, the airline sells the tickets on a large scale, which gives the airline authority to put some passengers on a later flight. If you cannot check in, then it may be why you held back for the flight that was scheduled later. If the space is available at the last minute, then you can check in.
The other reason is that you fall under the minor passenger category or have made a group booking; in those cases, you must check in at the airport.
