overall very good; just found a bit poor the food options in Narita airport but the in the flight it was good but limited (no real choice to avoid seafood or clearly stay away from pork..); most of the food was tasty tho and the choice was nice, specially their snacks and dessert and drinks. The in-flight systems was so-so (too complicated interface; they should rehaul with a proper UIX), and I specially appreciated their segments of videos capsules about the behind the scenes including an overview of technicalities of their aircraft and days in the life of their pilots. It was refreshing and give a good ideas of the efforts and challenges every employees has to deal with. Loved it!

FAQs about flying to Ireland

Ireland climate

The Gulf Stream gives Ireland a temperate climate, though given the lush countryside, there is lots of rain (categorised as soft rain, spitting, showers, or lashing and pelting). Summer is  typically dry and warm with long sunny days (it’s light from 6am-10pm) and average temperatures in the 20s. Spring and autumn temperatures are in the teens and winter is rainy and below 10 degrees.  It’s generally coldest in January and February and this is the best time to find cheap flights to Ireland. Ireland’s weather is notoriously changeable, so dress in layers. 

Getting around Ireland
