Travelers at Madrid’s main airport faced long lines and missed flights on July 2, 2025.
Official sources from Spain’s airport operator, Aena, and the National Police confirmed that too few police officers and a big increase in summer travelers caused the problem.
At Terminal 4, only half of the passport control booths were open during the busiest hours. This left thousands of people waiting in lines that lasted up to an hour.
The National Police added more officers later, but by then, many passengers had already missed their flights. Some people became upset, and the Civil Guard stepped in to keep things calm.
Aena said two things made the problem worse: not enough staff at passport control and a large number of travelers.
In May 2025, Madrid-Barajas Airport served 5.74 million passengers, which was one percent more than the previous year.
From January to May, the airport handled almost 27 million people, a 3.5 percent increase compared to last year. The airport’s passport control areas could not handle this growth.
The situation got even harder because Spain brought back temporary border checks from June 27 to July 5, 2025.

The government did this for security reasons during a big international meeting in Seville. These extra checks slowed things down even more.
Aena tried to help by making the train between Terminal 4 and its satellite run less often, so fewer people would arrive at passport control at the same time.
Even so, the small number of staff and the high number of travelers still caused big delays. Airlines like Iberia tried to help passengers who missed flights, but many planes left with empty seats.
