The Cheapest Days and Months to Fly GoWild (Availability by Calendar)

GoWild availability follows the demand calendar like clockwork. Here is the day-by-day and month-by-month cheat sheet for finding wide open flights.

The Cheapest Days and Months to Fly GoWild (Availability by Calendar)

By this point in the series you know availability is a demand forecast, not a coin flip. So let's turn that into a calendar you can plan a life around.

Days of the week, ranked

Months of the year

The blackout calendar already blocks the biggest holiday peaks, and demand handles the rest:

MonthsGoWild conditions
Late January, FebruaryExcellent, planes are empty after the holidays
April, May (outside spring break and Memorial Day)Very good
June, July, AugustMixed: high leisure demand, but also peak schedule with the most flights flying
September, OctoberExcellent, the best sustained window of the year
November, December (outside blackouts)Surprisingly good on the non-holiday days
GoWild conditions by monthDarker means easier. Blends demand patterns with blackout density; even light months hide gems.JanFebMarAprMayJunJulAugSepOctNovDecwide opengoodmixedhard: peaks + blackoutsFebruary, September, and October are the golden months.
The year at a glance for passholders.

Time of day matters too

The 6am departure and the 10pm departure are your friends. Nobody wants them, which is exactly why the pass loves them. Red-eye adjacent flying is the tax you pay for $15 airfare, and frankly, sunrise from a window seat is not much of a tax.

Put it together: a Tuesday 6:45am departure in late September is close to a guaranteed yes on most of the network. A Friday 5pm departure in July is close to a guaranteed no. Everything else lives on the spectrum between those two flights.

If you want the live version of this cheat sheet instead of the seasonal averages, that's what the WildFares calendar view is for: it shows GoWild pricing by date for any route, so you can see the pattern for your specific airport rather than the national trend.
