It hasn’t been long since dawn and the passengers are stretching one day in June 2025 thousands of meters above sea level. They left Philadelphia last night and are about to land in Naples. They are about to discover that, whether they slept better or worse, they are going to have a bad awakening.
And when they approach eight hours into the trip and already see the Italian coast on the screens in their seats, a voice informs them that they will not land in Naples. There is not much to fear, everything is in order. All. Except for a small bureaucratic error that is currently diverting them to Rome.
They will probably find out about that later. All they know is that their flight from Philadelphia to Naples has had to be diverted. And this time it was not due to a breakdown, a storm or a health emergency.
The reason is simple: the plane is too big to land in Naples.
Two meters that no one noticed
The Philadelphia-Naples route operated by American Airlines is a very good option if you want to travel from the United States to Italy and do not have the need to go through the large airports of New York or Rome. It also has the advantage that it flies at night, which makes it easier to deal with jet lag.
Encouragement that, surely, was appreciated by the 231 passengers who had to travel on a Boeing 787-8, according to C.B.S.. However, that day, the airline could have put someone else on board. And, for operational reasons, American Airlines used a Boeing 787-9 On that trip June 3, 2025, a plane slightly larger and with greater capacity than usual on a route that It has been operating since 2024.
The aircraft are almost carbon copies. Of course, a Boeing 787-8 measures 57 meters long but the 787-9 already extends to 63 meters long. A difference that has implications beyond the number of passengers. And, according to air safety regulations, a Boeing 787-8 can land in RFFS Category 8 airports (Rescue and Fire Fighting Services) or higher. But a Boeing 787-9 does not have it so easy, it needs to do it at airports in Category 9 RFFS.
The difference is small but it is substantial. A Category 8 RFFS airport can accommodate aircraft up to 61 meters long. Yes, two meters shorter than the Boeing 787-9.
And you can imagine what category Naples airport has.
Indeed, about 70 miles awaythe American Airlines flight asks for a runway in Naples but from the control tower someone realizes the problem: the aircraft is not the same as always. For logistical reasons, the airline was using this second, larger version of the Boeing 787 and therefore exceeded the maximum permitted limit of 61 meters. No one in the company updated the documentation or notified of the change.
Technically the problem is not in the size of the trackthe problem is in the security measures. And Naples is not prepared to deal with a possible incident involving a plane of this size. Airport categories are not only classified based on the size of the runway, but also take into account their ability to accommodate emergency and firefighting services.
From the control tower they see it clearly, there is no choice but to warn the pilots: they must land in Roma Fuimicino. The capital’s airport is the closest airfield where flights the size of a Boeing 787-9 can land and is therefore where the passengers were ultimately taken. From there, they were finally transferred by bus to Naples, a trip that takes between two and three hours.
A lesser evil for a problem that would have been much more serious if the aircraft had had a problem when landing.
