Dear Ellen, If you are going to Donegal, I would suggest Aer Lingus and Shannon Airport. Although it is a longer drive from Shannon, there is so much to see. The west coast is beautifel. You will be flying all night so you may not want to drive directly from shannon to Donegal (approx 8 hrs.) You will see that it is only abour 200-250 miles but when travelling in Ireland 30mph is the best you can hope for on average. Maybe you want to drive the first day to say Galway and continue your journey the next day. Another thought is that you may lood into derry to see if you can get anything. There is an airport in Donegal, but it has a short runway and flights are limited and i believe leave anly from Dublin.. If youhave any questions e mail me and I will be happy to answer what I can Joe
