Note the Ryan Air flight from Brussels Charleroi to Edinburgh on Wednesday 18 October has moved from 940am to 920am. I've changed my bus booking therefore to the 515am one as the 645am bus doesn't arrive till 830am which only leaves 50 mins for the flight which I reckon is a bit too tight. Bus price is same at 27 euros and you can change the bus ticket for free (need to cancel the first bus to receive a voucher which you can use to book the earlier bus, which costs the same at the moment).
