Local and regional events such as Phoenix Open (February), Barrett-Jackson Auto Auction (January), Fiesta Bowl (December/January), and Major League Baseball spring training (February–March) can cause spikes in economy fares leaving Phoenix Sky Harbor International Airport (PHX). National events—large conventions in Los Angeles, New York, or Chicago—also affect connecting flight prices and availability. For cheapest economy travel, avoid event weekends when local lodging and flight demand increase, or book far in advance if your trip coincides with major festivals.
The best months to find cheap economy fares from Phoenix Sky Harbor International Airport (PHX) are typically late January through early March and September, with shoulder-season windows offering lower demand. Mid-week departures (Tuesdays and Wednesdays) and red-eye flights often yield the lowest economy prices across domestic and short international routes. For holiday periods like Christmas and Thanksgiving, book several months in advance; for off-peak travel, a 3–8 week booking window can capture the best rates.
Nonstop flights from Phoenix Sky Harbor International Airport (PHX) are more convenient and reduce misconnection risk but may be pricier than connecting itineraries. Connecting flights through major hubs (Los Angeles, Denver, Dallas/Fort Worth) can unlock cheaper economy fares, but they increase total travel time and the chance of delays. When booking the absolute cheapest economy fares, weigh the savings against baggage transfer risks and tight layover windows. If you choose connections, allow buffer time—at least 60–90 minutes for domestic-to-domestic connections and 2+ hours for international transfers.
Southwest often offers competitive economy fares from Phoenix Sky Harbor International Airport (PHX) with the advantage of two free checked bags, making it a strong value even if the base fare is higher. Spirit and Frontier advertise rock-bottom base fares for the cheapest economy travelers but add fees for carry-on, checked bags, and seat selection. Legacy carriers (American, Delta, United) may run sales where the fully distributed cost competes with low-cost carriers, especially when baggage or schedule importance is considered. Always compare the total ticket price including add-ons and observe change or cancellation policies—some low-cost fares are nonrefundable and inflexible.
Summer: Book early for family travel and avoid midday heat when planning airport transfers; expect higher economy fares in June–July.

Winter holidays: Book months in advance for December travel and consider post-New Year departures for lower economy pricing. Spring (March–April): Watch for spring break spikes on popular routes; early and late spring often yield better fares than the peak weeks.
