Ryanair CEO Michael O'Leary stated on Thursday that airfare prices may experience significant increases if elevated oil prices persist, as the rising cost of jet fuel continues to pressure the airline industry. O'Leary noted that while pricing is expected to be modestly down in the second quarter (July to September), the outlook for the December and March quarters is uncertain. He added that the airline hopes to avoid such fare hikes. Brent crude prices edged above $100 a barrel on Thursday due to escalating tensions in the Middle East.
