And don’t forget to obtain your visa before departing (it can be done online or directly from the US embassy in Dublin).

Money saving tips

Since Chicago is a major hub for both United Airlines and American Airlines, it only makes sense to start your search with those. Also, Aer Lingus has a hub in Dublin so they also offer good fares (on the continent they actually compete with the low cost carriers’ fares).
