European airports have said jet fuel shortages could hit the summer holiday season, if oil supplies do not start to flow through the strait of Hormuz within the next three weeks.

Airports Council International (ACI) Europe wrote to Apostolos Tzitzikostas, the EU transport commissioner, saying the bloc is three weeks away from shortages.

The warning will raise concerns of a risk of flight or holiday cancellations if the US and Israel’s war on Iran continues. Oil prices have soared since the start of March after Iran effectively closed the strait of Hormuz, a key shipping route for exports from the Gulf, in retaliation.

“If the passage through the strait of Hormuz does not resume in any significant and stable way within the next three weeks, systemic jet fuel shortage is set to become a reality for the EU,” the letter said.
