The verdict

Roughly a wash: the midpoints are within about $50 of each other. (from Las Vegas, sample estimate, not live pricing)

Essentially a tie from both LAS and LAX. San Francisco's flight is short and cheap, but its hotels and restaurants are expensive; Lisbon's transatlantic fare is high, but rooms and meals cost far less. Pick on vibe: wine country and Golden Gate views, or pastel de nata, fado and old-world history.

Sources, notes & assumptions

Flight ranges come from typical round-trip economy fares that fare-search sites (KAYAK, Google Flights, Priceline, momondo, Expedia, airline fare pages) published for each route from each departure airport we cover (currently LAS and LAX), viewed October 2026. Lodging uses published hotel averages where we found them (Engine's August 2026 US city averages; Budget Your Trip traveler averages abroad), adjusted to a mid-range room; otherwise it is an editor estimate. Daily food, local transport and activity budgets are editor estimates for a mid-range couple; where a Budget Your Trip average exists we set the range around it, but the range bounds are our own judgment and have NOT been verified against a single published source. Ski lift tickets use published 2025/26 (or 2026/27) resort prices; euro and yen prices are converted at editor-assumed exchange rates. Taxes, resort fees, baggage fees and tips may not be fully included.

San Francisco

Last checked: 2026-10-17

Engine's Aug 2026 average for San Francisco is ~$165/night (cheapest public rate); range assumes a mid-range room in a central neighborhood, which typically costs more.

Portugal (Lisbon)

Last checked: 2026-10-17

Lodging assumes a 3–4 star central hotel; one comparison site reports 4-star Lisbon hotels averaging about €92/night, and peak-season rates run higher.

Assumptions: economy fares, 1 mid-range room, 7 nights / 7 days of spending, 2 adults. Excludes passports, travel insurance, checked-bag fees and souvenirs unless noted. Found a better number? Tell us.
