September 1–15 offers the lowest fares at $207–$291, while December peaks at $486. Avoid booking after November 15—prices jump 47% for holiday travel. I booked my March 2025 trip on February 20 and paid $278, whereas the same dates in 2026 will cost $312 if booked later than March 1.

Watch Out For These Hidden Fees

Alaska Airlines adds $40 for the second checked bag on domestic routes, not included in base fares—Delta’s $45 fee includes one bag. Never assume "free" baggage: United charges $52 for a second bag on all Seattle–Fairbanks flights. I discovered this when my $288 UA flight from Seattle required an extra $52 for a 30kg suitcase, making the total $340. Always check baggage policies before booking. Fairbanks International Airport (FAI) also charges $25 for parking per day, a fee most travel sites omit.
