Flight seasonality
US holiday windows (Thanksgiving, Christmas/New Year's, July 4th) and US school-break periods (spring break, summer) tend to carry the highest fares to Colombia, driven by general leisure travel demand rather than anything medical-tourism-specific.
Clinic scheduling seasonality
Clinics serving international patients often see demand cluster around the same US holiday and school-break windows, since patients frequently plan trips around time off work or school. Traveling outside those windows can mean both a cheaper flight and more scheduling flexibility at your preferred clinic.
Currency as a loose seasonal factor
Currency movement doesn't follow a reliable seasonal pattern the way flights do, but it's worth checking the exchange rate alongside your travel-date decision if your trip has scheduling flexibility — see SurgeryCost's currency exchange guide for the specifics.
The Takeaway
If your procedure timeline has any flexibility, shoulder-season travel is a low-effort way to capture both cheaper flights and better clinic availability at once.
