Rome
Overnight nonstops from the East Coast land by mid-morning. Two days covers the Colosseum, Vatican and Trastevere dinners; the jet lag works in your favor for early starts. Fly home Monday afternoon and you've spent one vacation day.
Lisbon
Among the shortest transatlantic hops — under seven hours from the East Coast — and one of the cheapest. Hills, tiles, pastel de nata, done. Shoulder-season fares here dip surprisingly low.
Dublin
Aer Lingus and U.S. carriers run dense schedules, and U.S. preclearance in Dublin means you land at home as a domestic passenger — the smoothest Monday-morning return in Europe.
Reykjavik
Five hours from the East Coast. Golden Circle on Saturday, Blue Lagoon on Sunday, northern lights if you're lucky. Icelandair's schedule is practically built for long weekends.
London
The obvious one, because it works: more U.S. nonstops than any overseas city means you can optimize the schedule to your office hours, not the other way around.
