Airlines on this route
No single carrier we cover has hubs at both FCO and LAX. American Airlines (at LAX), Delta Air Lines (at LAX), United Airlines (at LAX), and Alaska Airlines (at LAX) each operate a large network at one end, so many itineraries on this route connect rather than fly nonstop.
Nonstop availability on any route can shift from one season to the next, so treat this as a guide to who is likely to serve the market, not a timetable.
Common connection points
Connecting itineraries on this route often look like United Airlines via Denver (DEN), which adds about 70 miles (1% beyond the direct distance) or American Airlines via Phoenix (PHX), which adds about 180 miles (3% beyond the direct distance). Choose the connection with the best weather odds for your travel month and leave a comfortable layover; our layover guide explains how much time is realistic.
