Flight delays, cancellations and airspace closures are familiar concerns for travellers passing through the Middle East. Another aviation issue receives less attention: interference with the satellite navigation signals used by aircraft. Known as GPS jamming or spoofing, this interference can affect navigation information and add complexity to flight operations. In some circumstances, it can contribute to rerouting or diversions, with consequences for connections and onward travel.
For passengers, understanding the issue helps put the headlines into perspective. It is a recognised aviation safety concern that airlines and authorities are addressing, rather than something travellers are expected to identify or manage themselves.
What is GPS interference?
GPS is one of several satellite navigation systems collectively known as the Global Navigation Satellite System, or GNSS. Aircraft use these signals alongside other equipment to help determine their position.
Interference generally takes two forms:
GPS jamming disrupts reception of satellite signals, making them unavailable or unreliable.
GPS spoofing involves false signals that can cause a receiver to calculate incorrect position or timing information.
EASA, the European Union Aviation Safety Agency, identifies possible effects including inconsistent position readings and false terrain warnings. It also notes that interference can lead to rerouting or diversions. (easa.europa.eu)
Why is it relevant to flights through the Middle East?
EASA identifies the Middle East and Mediterranean among the regions where GNSS interference has increased, particularly around conflict zones and other sensitive areas. The issue also affects other parts of the world. (easa.europa.eu) You do not have to be visiting an affected country for the subject to be relevant to your journey. A flight between Europe and Asia, for example, may cross regional airspace or connect through a Middle Eastern hub.
However, reports of interference in a region do not mean that every flight encounters it, or that every encounter changes the flight schedule. Conditions vary, and the effect depends on the aircraft, its equipment and the circumstances.
Does GPS interference mean flying is unsafe?
GPS interference is a genuine safety issue. It does not automatically mean an aircraft has lost its ability to navigate. Aircraft can use other navigation sources, and aviation authorities provide guidance on recognising interference and managing its effects. EASA explains that awareness allows pilots to use alternative navigation aids to mitigate the rissk. Authorities are also updating their response. On 3 July 2026, EASA revised its safety bulletin following analysis of jamming and spoofing incidents. The update addressed crew training, communication between pilots and air traffic control, and other operational measures.
Earlier in the year, EASA and EUROCONTROL published a joint action plan intended to maintain safe operations and improve resilience to interference. For an individual flight, follow the airline’s instructions and relevant official travel guidance. A general report about GPS interference cannot establish the conditions affecting your particular route.
Could it cause a delay, diversion or missed connection?
It can contribute to operational changes, including rerouting or diversion. Whether passengers experience disruption depends on how the situation develops. A change to one flight can then affect the rest of a journey. A later arrival may mean missing a connection, collecting luggage at a different airport or rearranging a hotel and transfer.
That matters whether you are travelling for a business meeting, starting a family holiday or returning home with limited time between flights. It is also important to avoid attributing every unusual route or delay to GPS interference. Weather, air traffic restrictions, security conditions and technical issues can produce similar changes. The airline is the appropriate source for information about its operating decisions.
What should you do before travelling?
You do not need to monitor aviation navigation systems. The useful preparation is to make your journey easier to manage if plans change.
Check your airline’s updates
Make sure the airline has your current contact details and enable booking notifications. Check your flight status before leaving for the airport and again during a connection. Review official travel advice for your destination and any country where you may need to enter during transit.
Allow sensible connection time
A tight connection leaves little room for disruption from any cause. Where arrival time is particularly important, consider a longer connection or travelling a day earlier. Pay particular attention to separate bookings. If the first flight is delayed, onward arrangements may be more complicated than when the journey is booked together.
Keep essential information accessible
Save your booking references, accommodation details and assistance contacts where you can access them without relying entirely on an internet connection. Carry essential medication, charging equipment and immediate necessities in your hand luggage, within applicable airline and security rules.
Know who can help
Keep the airline’s contact details available, alongside those of your travel organiser, employer or assistance provider where relevant. Knowing whom to contact is especially useful when disruption happens overnight or in an unfamiliar country.
What if your flight is diverted?
Follow the crew’s instructions and wait for confirmed information about disembarkation, onward travel and baggage. Before arranging your own transport or buying a replacement ticket, establish what the airline is providing. A diversion does not necessarily mean you can enter the country concerned; immigration requirements and permission to leave the airport still apply.
If your arrival airport or timing changes, notify anyone expecting you and check whether your accommodation and transfer arrangements need updating. Keep booking confirmations and receipts for any additional expenditure. Where you need help understanding your options or coordinating practical arrangements, a travel assistance membership provides a point of contact alongside your airline and other travel providers.
Should you change your travel plans because of GPS interference?
A general report of GPS interference is not enough, on its own, to determine whether you should cancel a particular journey. Base that decision on current official advice, airline information, the wider security environment and your own circumstances. Travellers with essential appointments, medical needs or limited flexibility may want to allow more contingency time.
GPS interference is one part of the aviation risk picture. For travellers, the practical response is to stay informed, maintain contact with the airline and have support available if the journey changes. Global Traveller combines travel intelligence with 24/7 human assistance, helping members understand their options and coordinate appropriate support when travel does not go to plan.
