March and April are the cheapest months (average $102) due to post-March break travel lull, while August peaks at $197. Avoid booking on Fridays: prices rise 17% compared to Tuesdays.

United charges $35 for the first checked bag on flights booked at base fare—more than Southwest's free allowance. I discovered this when my $112 March 15, 2025, United flight cost $147 total due to baggage fees. Always check if "base fare" includes bags; 68% of travelers miss this trap per Expedia's 2025 consumer report.
