Travel days vary, and you'll need to play around with dates to make this one work, but it is available on select departure days in April and May. This is one of United's Basic Economy fares, so only carry-on luggage is included in this price. To check bags you'll have to dip into that pot o' gold and pay extra to put items in the hold.
I was able to find seats at this price departing PHX on Tuesday, April 16 and returning from DUB on Thursday, April 25, 2019.
We're noticing a lot of great deals out of SkyHarbor today, so make sure to take a gander at our Phoenix (PHX) departure page for a full listing of fare deals.
