About flying from Salt Lake City to London
London Heathrow (LHR) is the most-flown European route from Salt Lake City. Delta operates a daily nonstop with seasonal additional service; Virgin Atlantic and British Airways add capacity through codeshares and direct flights via SkyTeam and oneworld partners. Typical round-trip economy fares run $750 to $1,200, with flash sales into the $500 to $650 range several times per year and the occasional Delta or Virgin mistake fare below $400 RT.
Because Heathrow is a major hub, a deal to LHR often unlocks cheap onward routings to Paris, Amsterdam, Edinburgh, Dublin, and the rest of Europe. Utah travelers regularly use Deal Wings LHR alerts as a launch point for multi-city European trips.
Insider tip: London is one of the few routes where January and February consistently produce the year's cheapest fares: Delta and Virgin both run heavy post-holiday sales to refill transatlantic seats.
