The seats were very uncomfortable. I along with maybe 4 other passengers were never given our breakfast meal. The attendant completely forgot about us. For such a long flight the seats should be made with more comfort in mind. Just because it is economy doesn’t mean we don’t deserve comfort.

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

Using public transport (buses and trains) is fine for major routes such as Dublin to Cork or Galway, but trickier if you are travelling within counties.

Shoulder season: Spring and autumn are ideal times to visit, as the weather is normally still reasonably good and the bulk of the crowds have gone. Off season: Outside Dublin, it is cheapest to travel around Ireland in winter, however as tourism in many areas is seasonal, many hotels, restaurants and attractions close from early or mid-November until mid-March or Easter.
