Galway Airport
at Carnmore IATA: GWY is serviced by Aer Árann (http://www.aerarann.ie/). The schedule changes occasionally, but it may have flights to/from: Dublin, Belfast, Edinburgh, Manchester, Newcastle, Cork, Cardiff, Leeds Bradford, Bristol, London Luton, Lorient Brittany, and Waterford.

The airport is about 10km east of the town, but public transportation links are poor, with only three buses per day - and their times are not co-ordinated with flight times. If you do take this route please let them know this is poor!. A taxi cost €15 - €25 depending on traffic: this high rate is because the Airport charges €5 to taxis serving it. You could walk to a nearby address [5mins] and call a taxi from there, saving €5.

Car Rentals are available.
