Dear Ellen ~ We have flown from BWI to Ireland twice -- once to Dublin and once to Shannon. We prefer Shannon. It's a much smaller airport, easier to get around, has considerably less traffic and is on the west side of the country so more easily accessible to Co. Donegal (where we also have family.) You'll leave BWI in the evening (about 7 p.m.) and be in Shannon by morning.) We traveled Aer Lingus both times (the Irish airlines), but there are US airlines that fly there also. Aer Lingus planes are very comfortable and roomy. You might want to post your questions to this group -- it's great and every one of my questions has been answered in the past: [email protected] Aer Lingus site: http://www.aerlingus.ie/cgi-bin/obel01im1/index.jsp Sincerely, Tamy in Nevada, USA
