Iberia issues an urgent warning to travelers arriving at Barajas Airport following the collapse of passport control.

With the first few minutes of July comes the dreaded Operation Exit , with millions of people already preparing to enjoy their long-awaited summer vacations . In the coming hours, many will have to board a plane from our country's airports to begin their days of rest.

Once again, Adolfo Suárez Madrid-Barajas Airport will be the hub with the most flights operated this summer, with around 180,000 passengers passing through each day. However, the large influx expected this weekend is already beginning to worry travelers and airlines. Many fear a repeat incident like the one that occurred a few days ago at the capital's airport.

The chaos at Barajas Airport , caused last Wednesday by "a computer failure in accessing the applications used by the National Police," ended with endless lines at passport control at Terminal 4 Satellite (T4S). According to police sources, all of this coincided with a "pile of flights" within a "very short" period of time, which meant many passengers ended up missing their flights.

Airlines do not rule out a similar situation this weekend, where traffic will increase significantly due to this new departure operation. To try to control this flow and prevent a possible repeat congestion at Madrid airport, some airlines have begun sending alerts to travelers with flights scheduled for the coming days.

One of the first to do so was the Spanish airline Iberia , which issued a recommendation to its customers to prevent further incidents like this from happening.

In a scheduled email sent to those traveling in the coming hours, the company has reminded passengers that "passport control at Madrid Airport is experiencing wait times of over 40 minutes ." Therefore, they advise passengers traveling outside the EU to arrive several hours in advance.

" Make sure you arrive at least four hours in advance to check in and drop off your luggage and head directly to Terminal T4S to avoid any inconveniences," warns this email, which hundreds of Iberia customers have received in the last few hours.

The airline has been working for years to improve the customer experience and also speed up airport waiting times. A few days ago, the company launched a dynamic boarding pass that notifies passengers of seat or gate changes in real time.

The goal is to facilitate the boarding process for travelers and optimize operational times. This feature is available in the Iberia app (both for iOS and Android) and for customers who download their boarding pass to Apple Wallet or Google Wallet from the website.
