Hi Ms V -
Wanted to tell you that, although I'd flown before, it terrified me too. I hated it. But after 2 trips to Ireland in the space of a few months, I don't even think about it any more. Really, if you fly over an ocean once, you'll do it again, I think, by virtue of having survived the first time!
And if you don't shop while you're over there, it's surprisingly affordable. Fm NYC, the flight in only $800. Although there've been some shake-ups w/airlines over there so it can be difficult going anywhere other than Dublin. (Course that's only my [limited] experience talking. Also, I'm referring to Rep of Ire -- not N. Ireland.) Bus travel may be necessary or Cork. I flew into tiny Galway airport last year but this year the same flight is not available. (I had to cancel my reservations this year cuz I've been out of work since Dec.)
