Cannot check in on line

I travel on a weekly basis and the only reason I book Comair is due to flight times and pricing (dictated by my work's policy).<br> <br> On a regular basis I have either check in problems (cannot check in on line) or flights are delayed. This includes BA and Kulula flights.<br> <br> I always like to check in asap to get a good seat. Tonight when trying I could not check in, as it was after hours, I could not get through to any call centre. Eventually I tried the Slow Lounge and the person there was extremely helpful. However, I was still booked far from the front (after only 45 minutes of checking in opening up). She could still not open up my booking to allow self check in and she could only pre book the seat, but not check me in. <br> <br> This has happened to me several times before and this is definitely some system issue which you need to resolve. Continually shocking service and the only reason I use Comair is as stated, pricing and times of flights. If I had my own way would never use you unless you can improve your systems and operations.
