Plan and book early for summer and holiday travel; use flexible-date searches to find the cheapest economy tickets.

Contact the airline directly or use their app to review upgrade options and fees.
Arriving at Denver (DEN) FAQs
'Cheapest Economy Fare (ECONOMY)' refers to the least expensive standard economy or basic economy available for a given route, often with limited baggage and seat-selection privileges. When planning arrivals, factor in additional fees for checked bags, seat assignments, and transfers from the arrival airport to your final destination like downtown Los Angeles, Las Vegas, Phoenix, or Dallas.

In June, arrival prices for cheapest economy seats can rise because of summer tourism, conventions, and events in major cities; rates to coastal and resort destinations often increase. Booking several weeks in advance and avoiding weekend arrival dates can help secure lower fares. Use flexible-date tools and consider alternate nearby airports to find better prices for June travel.
Cheapest economy tickets often exclude checked baggage and may limit carry-on size; verify baggage allowances before arrival to avoid unexpected fees. For transfers, budget additional time for baggage claim and TSA screening if connecting domestically or internationally, and consider booking ground transfers or rideshares in advance for major arrival hubs like Los Angeles or New York to ensure timely onward travel.
Upgrades from cheapest economy fares depend on the airline; some allow paid upgrades at booking or during check-in, while deeply restricted fares might be non-upgradeable. Check the airline’s upgrade and refund policies immediately after purchase and monitor for upgrade offers via email, the airline app, or at the gate.
