As fuel costs rise, the price of airline tickets will go up without doubt.

As economies recover from the Covid pandemic and the war in Ukraine, the price of oil has gone up.

Willie Walsh said that the costs would be passed on to consumers.

The former British Airways boss said that the airport should have prepared better.

Mr Walsh said that holidaymakers need to be aware of the cost of flights.

He said that the high price of oil will have an effect on ticket prices.

As demand picked up again in economies that had started recovering from the Covid epidemic, oil prices were going to go up as well.

Prices have gone up due to the war in Ukraine. The UK will phase out Russian supplies by the end of the year after the US banned oil imports from Russia.

Most Russian oil imports will be blocked by the end of the European Union's term.

Demand for oil from other producers has gone up.

Mr Walsh said that oil was the single biggest element of an airline's cost base and that fuel prices were at a record high.

Consumers will pay higher ticket prices because of the high oil prices.

Airline passengers in the UK have had to deal with flight cancellation due to major disruption at some airports.

Passengers who have their flights canceled may not have to pay more for rebooking.

He said airports that can't cope should adjust their schedules so that they can accommodate more people.

There have been problems recently with the baggage system at the airport.

Heathrow should have prepared better.

They wanted airlines to operate 80% of their slots through the summer.

You would have to be critical of Heathrow because they didn't have enough resources to deal with it.

While acknowledging that many of the issues affecting airlines and airports were caused by staffing problems, Mr Walsh said that he had "no regrets" about making deep cuts to British Airways' staff during the swine flu epidemic.

The airport has been contacted.
