What is the best month to fly and avoid delays?
Choosing the right month to travel can be just as important as choosing the destination or airline. Flight data from 2025 analyzed by Flightright confirms that delays and cancellations are not randomly distributed throughout the year: they follow a fairly predictable pattern. Knowing this is a clear advantage for those planning business or personal trips and wanting to minimize unforeseen events.
February, the most reliable month to fly from Spain
If the goal is to reduce the risk of incidents on domestic flights, February clearly stands out. It was the month with the lowest percentage of delays (25.36%) and one of the lowest cancellation rates of the year (0.17%).
January and April are also among the most stable months, with delay levels below 29%, making them good alternatives for planning trips further in advance.
At the opposite end of the spectrum is July, the most problematic month of the year. Almost four out of ten flights were delayed (36.95%) and cancellations reached their annual peak (0.65%). Furthermore, the effect is not limited to the summer: August, September, and October maintained high levels of incidents, all above 32% of delayed flights. Operational congestion, therefore, extends beyond the peak holiday season.
April, the best month to fly in Europe
At the European level, the pattern is similar, although with one month clearly standing out. In 2025, more than 8.3 million flights were operated in Europe, and nearly one in three experienced delays. In this context, April was the most stable period for flying across the continent: 28% of flights were delayed and it had the lowest cancellation rate of the year (0.35%).
Once again, July had the worst results in Europe, with almost 38% of flights delayed and the highest percentage of cancellations (0.82%). For international travel, choosing April can make a real difference to the passenger experience.
Plan better... and know your rights
The data confirms that traveling outside the busiest months significantly reduces the risk of incidents. As Lucía Cegarra, legal expert at Flightright, points out, when problems occur, "they are not random, but predictable," and it is also worth remembering that passengers have rights and, in many cases, the possibility of claiming financial compensation.
For travel managers, mobility managers, and frequent travelers, the message is clear: the calendar is also a management tool. Anticipating dates, avoiding the busiest months, and knowing your passenger rights allows you to save time, reduce indirect costs, and travel with greater peace of mind.
