Salt Lake City is a Delta hub at the foot of the Rockies, and its cheapest flights point firmly across the Atlantic — a tight cluster of European fares from Reykjavik to Brussels that give the Mountain West a direct-ish reach into Europe.
Salt Lake City International (SLC) has one of the best airport-to-city links in the US: the TRAX Green Line runs from a station right on Level 1 of the terminal (no shuttle needed) straight into downtown — Temple Square, City Creek, Gallivan Plaza — in about 20 minutes for a flat $2.50, trains every 15 minutes at peak. After a flight, walking from baggage claim onto a train into the centre for pocket change is hard to beat. Most visitors heading to the ski resorts or national parks rent a car, but for downtown, the Green Line is the obvious, cheap choice.
As a base, Salt Lake City is squarely a transatlantic-leisure airport. There’s little cheap short-haul here — the value is a cluster of European fares that let the Mountain West skip a coastal connection for the European trip.
Iceland and Ireland — the cheapest entries
The two cheapest fares are the classic gateways. Reykjavik (€612) leads — Iceland itself, plus a connecting point onward into Europe — with Dublin (€660 with a bag) following, the latter offering US preclearance on the way home (you clear immigration in Ireland and arrive back as a domestic passenger). For a first hop across the Atlantic from the Mountain West, these two are the best-value picks.
Spain, Italy and the Low Countries
The rest of the board fills in the European map. Barcelona (€672) opens Catalonia direct, Milan (€733) reaches northern Italy and the gateway to the Alps and lakes, and Brussels (€735) covers the Low Countries and the EU’s de facto capital. These cluster within about €60 of each other, so it’s worth watching which dips first — all are reasonable transatlantic fares for a hub of Salt Lake’s size, and each saves a coastal connection.
Why Salt Lake for Europe
Salt Lake’s pitch is its Delta hub plus its gateway role for the Mountain West. For travellers in Utah, Idaho, Wyoming and beyond, SLC is closer and easier than Denver or the coastal hubs, and on these European leisure routes the fares price competitively. The trade-off is fewer non-stops — most connect through a European or US hub — so flexibility on a single stop usually unlocks the prices shown.
A note on these US-origin fares
This is a leisure-transatlantic board, and the figures are the lowest verified levels — they move sharply by season. European fares from the US West are cheapest outside the summer peak: spring, autumn and deep winter hide the best numbers. Because Delta dominates SLC, watch for its sales — the European fares drop noticeably when a promotion runs.
