Since the war in Ukraine began, Western airlines have rerouted flights south through the Middle East to avoid Russian airspace. However, escalating tensions in regions like Israel and Iran are making it increasingly difficult to navigate these routes safely. Both Iran and Israel have been accused of GPS spoofing, a technique that sends false location signals to satellites. While intended to misdirect attacks away from civilian targets, this practice also disrupts GPS systems used by civilians, including aircraft, creating significant safety risks.
In March, a Turkish airliner bound for Beirut had to turn back due to a spoofed GPS signal preventing a safe landing. The U.S. Federal Aviation Administration (FAA) has since warned pilots flying near conflict zones about these risks. As tensions rise, especially with Iran, several airlines, including Delta, United, and Lufthansa, have temporarily suspended flights to high-risk areas like Tel Aviv and Beirut.
The instability also affects key air routes between Europe and the Middle East, particularly those passing over northern Iraq near Iran. In September 2023, multiple planes reported losing GPS signals along this route, with one business jet nearly entering Iranian airspace without clearance. OpsGroup, which monitors aviation risks, reported a 400 percent increase in GPS spoofing incidents, impacting about 900 flights daily.
In response to these escalating risks, some airlines, including Singapore Airlines and Finnair, have decided to avoid Iranian airspace, leading to longer flight times. Meanwhile, Russian GPS spoofing has also disrupted flights in neighboring countries like Lithuania and Estonia, prompting temporary route suspensions.
Despite these challenges, not all airlines are avoiding Russian airspace. Chinese airlines, benefiting from their ability to fly over Russia, have expanded their services to Europe and the U.S. For example, Air China introduced new flights to London as British Airways prepared to exit Beijing. Chinese airlines can offer shorter flight times compared to Western carriers due to their use of Russian airspace, giving them a competitive edge.
The Biden administration has approved more flights from China on Chinese airlines, though some U.S. lawmakers have objected, citing unfair market advantages. This concern is echoed by European carriers like Air France-KLM, whose CEO has called for a ban on flights over Russia landing in Europe.
The ongoing geopolitical tensions are disrupting global air travel, creating an uncertain future for Western carriers, while some Chinese airlines continue to capitalize on these challenges.
