Hi, I'm doing some contingency planning for a trip to Dublin this weekend. I'm booked on Aer Lingus from Heathrow on Sunday. I'm a medical courier and need to get there by midday on Monday to collect cells for a patient in the UK. With the Heathrow bother I'm unsure whether my booking will be honoured. The return journey is to Manchester so that should be OK. If I was to use train+ferry what are my options?
