EI are simply great for the price of their tickets. I've flown MUC-DUB-MUC 4-5 times this year already and always for under €100.
For this price you get very friendly service, great smiles and a welcome, food/beverages for a surcharge (but for a cheap ticket and 2hr flight and cheaper than at airport, who cares!!)
All flights were well on time and the airbus 320/321 were new, clean and comfortable.
Only minus point, no entertainment and no in-flight magazines on board. But who doesn't travel without reading material nowadays??!!
Aer Lingus (EI) is definitely to recommend as number 1 from Munich to Dublin, Cork and Belfast :)
