Round trip tickets just appeared for Sep 1 – Sep 6 from Miami (MIA) to Dublin (DUB) for $445. There’s a short stop in Madrid (this fare is typically $800+). Won’t last long.
Not to mention, you’ll be flying British Airways. Look who’s fancy now! The flight takes off right after you end your workday on the Friday before Labor Day weekend and will fly you back in time for happy hour on hump day. Screenshot of the fare is below. Grab the deal here.
