My siblings and I purchased our parents a trip to Ireland for Christmas. They are leaving from either Tampa, FL or Ft. Myers FL and flying in to Dublin. The trip takes place in October. I am in the process of getting their airfare.... the only problem is I don't know who to use! I've only flown in the US and only on Delta flights. Since I have no experience with the other airlines I don't know how they compare. Are they clean? How is the customer service? Any complaints? W are going to fly them Economy Class - I know that makes a difference :) Aer Lingus has some of the cheapest fares that i've seen, but i'm afraid if I base it on price alone they will have a horrible journey. Any advice?
