For MSY–LHR we show about $389 on the low end and around $695 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $389 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.

Distance and time MSY–LHR
New Orleans and London sit about 4,621 miles apart. If a nonstop is missing from MSY, timed itineraries near 9.5 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
London is about 6 hours ahead of New Orleans on standard time (America/Chicago vs Europe/London). Arrival clocks on LHR are local. That matters more on this pair than on a same-zone hop.
Most New Orleans–London journeys connect rather than fly nonstop from MSY. Timed one-stop itineraries often bank at John F. Kennedy International (JFK), Newark Liberty International (EWR), O'Hare International (ORD). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
