Virgin Blue is still experiencing delays at Brisbane Airport after the airline's check-in system had to again be restored this morning.

The glitch lasted less than two hours but it has continued to cause problems.

All flights scheduled to arrive in Brisbane this afternoon are delayed and a Hobart service due to arrive in Brisbane at 1.45pm was cancelled.

Departures are faring better, with all destinations except Sydney leaving Brisbane Airport within 30 minutes of their allocated time.
