Most of us with an interest in Irish genealogy (or those who just want a nice vacation) frequently look at plane flights to Ireland. Usually the rates are high if you would like to go during the usual tourist season.
If you see a good rate on a flight to Ireland often there is some sort of exclusion like “good on flights during February”. We were very surprised a few nights ago when we saw Ireland flights on sale. The best prices were New York to Shannon but decent enough prices for flights with other origins and destinations.
So check out the Aer Lingus sale on Ireland flights as well as their offers to elsewhere in Europe. There may be a reasonably-priced vacation in your future.
