A government spokesperson said UK airlines were “clear that they are not currently seeing a shortage of jet fuel”.
The closure of the Strait of Hormuz as a result of the conflict in Iran has had a dramatic impact on jet fuel prices and raised concerns about possible shortages in the months to come.
Europe, and the UK in particular, are usually highly reliant on imports from the region, and have been scrambling to find alternative supplies.
Last week, for example, the EU said there was no regulatory reason why US-grade jet fuel should not be used by European airlines, provided its introduction was managed carefully.
On Wednesday, the EU’s energy commissioner, Dan Jorgensen, said he did not expect a serious shortage in the short term, but could not rule out supply issues in the longer term.
The chief executive of the travel operator Tui, Sebastien Ebel, also said he did not expect shortages over the coming months.
But Walsh said there were still concerns for UK operators.
“I think the major problem facing the UK is timing,” he explained. “You normally expect to see a 25% increase in flights and fuel requirements in the months of July and August versus, let’s say March.
“I think the concern will be that if sufficient alternative supply isn’t sourced, there may be some shortages when we get into the peak summer period.”
However, he stressed that there was no reason to panic, and that widespread cancellation of flights could be avoided.
