Tokyo, June 12 (Jiji Press)--Japan Airlines and All Nippon Airways will raise their fuel surcharges added to airfares to record levels of about 65,000 yen for tickets to be issued in July and August for flights from Japan to North America and Europe, it was learned Friday. The higher surcharges, which reflect surges in aviation fuel prices blamed on the Middle East crisis, could dampen travel demand during the summer holiday season. Fuel surcharges are calculated based on the average of aviation fuel market prices and of foreign exchange rates over the past two months. The two major Japanese airlines are also expected to raise the caps on their fuel surcharges to around 70,000 yen. The July-August surcharges will be lower than the ceiling as JAL and ANA plan to use government subsidies. For tickets in May and June for flights to North America and Europe, JAL raised the surcharges to 56,000 yen from 29,000 yen in April, and ANA to 56,000 yen from 31,900 yen.
