A Ryanair flight travelling from Seville to Nantes declared a fuel emergency and diverted to Brest after an unrelated aircraft incident temporarily blocked the runway at Nantes Atlantique Airport.
Flight FR5448, operated by a Boeing 737-800, landed safely at Brest Bretagne Airport on the evening of Monday, 6 July 2026. No injuries were reported.
The emergency developed after the Ryanair aircraft was forced to abandon its approach to Nantes, spend additional time holding in the air and then divert as its fuel reserves reduced.
What happened to Ryanair flight FR5448?
Ryanair flight FR5448 was operating a scheduled service from Seville Airport in Spain to Nantes Atlantique Airport in western France.
The aircraft, identified in aviation reports as Boeing 737-800 registration EI-EBK, departed Seville at approximately 5.25pm local time and was expected to arrive in Nantes at around 7.10pm.
The flight reportedly operated normally until it approached Nantes.
As the aircraft lined up to land on runway 21, the crew was unable to complete the landing because the runway had become temporarily unavailable.
The pilots performed a go-around, climbing away from the airport rather than continuing an unsafe or unavailable landing attempt.
Why was the Nantes runway closed?
The runway disruption was linked to a separate emergency involving Air Nostrum flight IB1222.
The Mitsubishi CRJ-1000 had departed Nantes for Madrid but reportedly suffered an engine problem shortly after take-off. Initial aviation reports suggested that debris from a burst tyre may have contributed to the engine failure.
The Air Nostrum aircraft returned to Nantes, while debris and the emergency response left the airport’s only runway temporarily blocked.
Because Nantes Atlantique operates with a single main runway, the incident affected several arriving aircraft and led to diversions across the region.
An inspection later identified debris on the runway. Flight operations were suspended for almost four hours before traffic resumed at approximately 11pm local time.
Why did FR5448 declare a fuel emergency?
After abandoning the Nantes approach, the Ryanair crew climbed to around 7,000 feet while air traffic control and the pilots assessed whether the runway would reopen.
The aircraft then entered a holding pattern at approximately 4,000 feet.
Holding allows an aircraft to remain near an airport while waiting for landing clearance, but it also consumes additional fuel.
As the runway remained unavailable and the flight continued using its reserves, the captain declared a fuel emergency. This gave the aircraft priority handling from air traffic controllers.
The flight then climbed to around 20,000 feet and headed directly towards Brest Bretagne Airport.
Where did Ryanair FR5448 divert?
The aircraft diverted to Brest Bretagne Airport in Brittany, north-western France.
Brest was a practical alternative because it had an available runway and was within the aircraft’s remaining operational range.
Flight FR5448 landed safely on runway 25L after approximately two hours and 40 minutes in the air.
There were no reports of injuries among passengers or crew.
Did Ryanair FR5448 run out of fuel?
No. The aircraft did not run out of fuel.
Its engines remained operational, and the flight landed safely in Brest.
A fuel emergency does not necessarily mean that an aircraft is moments away from engine failure. It means that the crew has determined that the available fuel has reached a level where further delay could compromise the required final reserve.
The exact quantity of fuel remaining when FR5448 landed has not been publicly confirmed in the reports available so far.
Claims suggesting that the aircraft had only a specific number of minutes of fuel remaining should therefore be treated cautiously unless confirmed by Ryanair, investigators or an official technical report.
What is a fuel emergency?
In commercial aviation, pilots continuously monitor how much fuel remains and how much will be needed to reach the destination or an alternative airport.
An aircraft carries fuel for several purposes, including:
- The planned journey
- Taxiing before take-off
- Unexpected delays or weather
- Diversion to another airport
- A protected final reserve
Pilots may advise air traffic control that they are operating with “minimum fuel” when further delays could become problematic.
A Mayday fuel emergency is more serious. It is declared when the aircraft is expected to land with less than its required final reserve fuel.
The declaration allows air traffic controllers to prioritise the aircraft and reduce the risk of further delay.
Was the go-around itself dangerous?
No. A go-around is a standard aviation safety procedure.
Pilots perform one when a landing cannot be completed safely, whether because of runway conditions, another aircraft, weather, an unstable approach or instructions from air traffic control.
In this case, the runway was unavailable because of the separate Air Nostrum emergency.
The concern arose not from the go-around itself, but from the additional flying time caused by the blocked runway, holding period and diversion.
FR5448 emergency timeline
Around 5.25pm
Flight FR5448 departed Seville for Nantes.
Around 7.10pm
The aircraft approached Nantes and prepared to land on runway 21.
Nantes approach abandoned
The runway became unavailable following the emergency return of Air Nostrum flight IB1222.
Aircraft entered a hold
The Ryanair flight remained near Nantes while the crew and air traffic control waited to see whether the runway could reopen.
Fuel emergency declared
As the delay continued and fuel reserves reduced, the captain declared an emergency.
Diversion to Brest
The flight climbed and received priority routing towards Brest Bretagne Airport.
Safe landing
The Boeing 737-800 landed safely on Brest’s runway 25L after about two hours and 40 minutes of total flight time.
What happened to the Air Nostrum flight?
Air Nostrum flight IB1222 was travelling from Nantes to Madrid when it experienced an engine-related emergency shortly after departure.
The aircraft returned to Nantes, creating the runway blockage that affected FR5448 and other inbound services.
Early reports indicated that a burst tyre may have scattered debris and contributed to the engine issue. However, a complete official investigation or final technical finding has not yet been publicly identified.
It is therefore important to describe the tyre-debris explanation as preliminary rather than confirmed.
Were other Nantes flights affected?
Yes.
The runway closure disrupted arrivals and departures at Nantes Atlantique Airport.
Incoming aircraft were diverted to other regional airports while ground crews inspected and cleared the runway.
The airport’s dependence on one runway meant that the separate aircraft emergency had a significant knock-on effect across the schedule.
Traffic reportedly resumed at about 11pm after inspections were completed and debris was removed.
What happened to passengers after landing in Brest?
The available reports confirm that passengers and crew landed safely, but detailed information about onward transport, hotel arrangements or the eventual journey to Nantes has not yet been clearly established.
Ryanair would normally be responsible for communicating with affected passengers about onward travel and assistance following a diversion.
Passengers should retain boarding passes, receipts and airline communications if they incurred reasonable expenses because of the disruption.
Are passengers entitled to compensation?
Passengers may be entitled to care and assistance when a flight is diverted or significantly delayed.
This can include food, refreshments, communication and, where necessary, accommodation or alternative transport.
However, fixed financial compensation under European air-passenger rules depends on the cause of the disruption.
Because the FR5448 diversion appears to have resulted from an unrelated aircraft emergency and runway closure, Ryanair may argue that the event involved extraordinary circumstances outside its control.
That could remove the requirement to pay standard delay compensation, although the airline’s obligation to provide care and rerouting may still apply.
Eligibility will depend on the final arrival delay, the assistance provided and the precise circumstances of the incident.
Has Ryanair issued a statement?
At the time of writing, no detailed public Ryanair statement explaining the full sequence, remaining fuel level or passenger arrangements had been identified in the available reporting.
The confirmed position from current aviation reports is that the aircraft declared a low-fuel emergency, received priority handling and landed safely in Brest.
Further information could emerge from Ryanair, Nantes Airport, Brest Airport or French aviation authorities.
Was the aircraft unsafe before leaving Seville?
There is currently no evidence that FR5448 departed Seville with insufficient fuel or with a known technical defect.
The flight reportedly proceeded normally until the unexpected runway closure at Nantes.
Commercial fuel planning includes allowances for diversions and contingencies, but unpredictable airport closures can force crews to reassess their options quickly.
Declaring an emergency is part of that safety process. It allows the crew to obtain priority rather than continue holding and risk reducing the reserve further.
Is an investigation underway?
No formal investigation announcement has yet been identified in the available sources.
Aviation authorities may still review the event, particularly the Air Nostrum engine problem and runway debris that triggered the wider disruption.
Any official inquiry would likely examine:
- The cause of the Air Nostrum emergency
- How debris reached the runway
- The duration of the Nantes runway closure
- Air traffic control instructions
- FR5448’s fuel status and diversion decision
- The assistance provided to passengers
Until official findings are published, the precise fuel figures and technical causes should not be presented as confirmed facts.

What the FR5448 incident shows
The FR5448 emergency was not caused by a reported fault on the Ryanair aircraft itself.
It developed because an unrelated emergency shut Nantes Airport’s runway just as the Ryanair flight was preparing to land.
The crew initially waited for the situation to clear but later declared a fuel emergency and diverted to Brest.
The aircraft’s safe landing demonstrates why pilots declare emergencies before a situation becomes more critical. The declaration secured priority routing and allowed the flight to reach a suitable alternative airport without further delay.
