Executives of major low-cost airlines are set to meet tomorrow with US Transportation Secretary Sean Duffy as they urge Congress to provide temporary tax relief to partially offset the soaring cost of jet fuel sparked by the war with Iran, Al Jazeera reports.

A group representing Spirit Airlines, Frontier Airlines, Allegiant Air, Sun Country and Avelo last week wrote to leaders in Congress asking lawmakers to pass legislation to suspend the 7.5 per cent federal excise tax on airline tickets and a $5.30 per segment tax.

Waiving the fees would offset about one-third of the incremental cost of higher jet fuel, the Association of Value Airlines has said.
