Flights to tourist hotspots have been cancelled following Donald Trump’s attack on Iran, with the UK Foreign Office issuing a new warning to prospective travellers. British Airways cancelled all flights from London to Dubai and Doha, Qatar, on Sunday, after a plane was diverted to Zurich when the US struck nuclear sites in Iran on the weekend. Britain was among the main contributors to Qatar’s tourism industry in 2024, and over a million Brits visited Dubai during the same period – marking a 14% year-on-year rise.

The Foreign Office issued a new travel warning for UK citizens planning to travel to the United Arab Emirates city, which lies around 80 miles from the Iranian mainland, on Sunday – urging caution as the Iran-Israel conflict continues to heat up. “Ongoing hostilities in the region and between Israel and Iran have the potential to deteriorate further, quickly and without warning, including since US military strikes against Iran on June 22,” the updated guidance read.

Foreign Office officials warned that while travellers who have a valid passport or visa “shouldn’t face difficulties” entering the UAE, tourists should double-check their documents before setting off.

“Check with your travel provider that your passport and other travel documents meet requirements,” the guidance urged. “The authorities in the UAE set and enforce entry rules. If you’re not sure how these requirements apply to you, contact the UAE Embass in the UK.”

Brits could also face potential travel disruption in the region, officials said, potentially including last-minute airspace closures and flight delays or cancellations.

A similar warning was issued for those planning to fly to or from Qatar, with the foreign affairs ministry preparing UK visitors for the possibility of “unanticipated travel impacts” linked to the Iran-Israel war.

Following the confirmed flight cancellations between London and the two tourist hotspots on Sunday, British Airways said the “schedule adjustment” was to “ensure the safety of our customers and crew … while we work through this developing situation”.

Israel also announced that it had closed its airspace to both inbound and outbound flights after the US targeted three Iranian nuclear sites early on Sunday morning.

Donald Trump‘s administration struck three facilities, including the Fordo uranium enrichment site, which is located in a mountainous region around 60 miles from the Iranian capital Tehran.

The strikes prompted Iran to launch a retaliatory bombardment of ballistic missiles against Israel over the weekend, with the country’s officials warning that its military had been given a “free hand” to attack American targets.
