Los Angeles (LAX) → Denver (DEN): cheap fares overview
LA to Denver is one of those domestic routes where prices can swing wildly depending on what's happening at either end. Ski season — roughly Thanksgiving through March — pushes fares up hard because half of Southern California wants to get to the Rockies on the same weekends. Summer hits a second spike as families road-trip alternatives and festival crowds descend on Colorado. The sweet spot tends to be shoulder seasons: late April through May, and again in October. All five carriers flying this route — including WN and F9, which tend to price aggressively — compete enough to keep base fares reasonable outside peak windows. At under two hours direct, there's rarely a reason to book a connection.
Why travel from Los Angeles to Denver?
Denver punches above its weight in ways that still surprise people who've only thought of it as a ski town. Yes, you're within easy reach of world-class skiing at Breckenridge and Vail, but the city itself has genuinely good food — the Platte Street and RiNo neighborhoods alone could fill a weekend. There's a serious craft beer scene, a thriving live music circuit, and a walkable downtown that feels nothing like the sprawl of LA. For remote workers, Denver's cost of living is meaningfully lower than Los Angeles, which makes it a popular longer-stay option. A lot of Angelenos have family who relocated here during the pandemic and never came back. And DEN connects onward to 235 non-stop destinations, so it works well as a hub if you're continuing somewhere else.
How to find a cheap fare on this route
Book at least three to four weeks out for leisure travel on this route — last-minute fares spike fast, especially Friday evenings and Sunday afternoons when business travelers fill the same planes. If your dates are flexible, mid-week departures on Tuesday or Wednesday consistently come in lower. F9 and WN both run sales on this corridor, so it's worth checking their direct sites alongside aggregators. Avoid Thanksgiving week and Presidents' Day weekend entirely unless you're booking months ahead. There's no obvious alternative airport worth the detour on either end — Ontario and Long Beach serve different parts of LA but rarely beat LAX on this specific route.
Frequently asked questions
What is the cheapest month to fly from Los Angeles to Denver?
Typically, shoulder seasons like April-May and September-October offer lower fares than peak summer and winter holidays. Flying mid-week (Tuesday-Thursday) generally provides better prices than weekend departures.
How far in advance should I book a flight from Los Angeles to Denver to get the best price?
Booking 1-3 months in advance typically offers the best fares for this route. However, monitoring prices continuously and setting fare alerts can help you catch deals even with shorter booking windows.
Should I book a direct flight or connecting flight from Los Angeles to Denver?
Direct flights (approximately 1 hour 38 minutes) are available and often more convenient, though they may cost slightly more than connecting options. Connecting flights save money but add 2-4+ hours to your travel time, making them worthwhile only for major savings.
What payment methods and currency should I use when booking flights between Los Angeles and Denver?
Both cities are in the USA, so you'll pay in US dollars using standard payment methods like credit cards, debit cards, or digital wallets. No currency conversion is needed for this domestic flight.
What should I know before booking a cheap flight from Los Angeles to Denver?
Check baggage allowances with your carrier (AA, DL, F9, UA, or WN all serve this route), as budget airlines like Frontier (F9) may charge for carry-ons or checked bags. Also verify seat selection policies and cancellation terms, as cheaper fares often come with restrictions.
