Mercury Air Group has announced that its website, www.mercfuel.com, is open for flight departments and pilots who enter into a fuel sales agreement with Mercury. Using a password, customers will be able to order jet fuel before a flight or en route at numerous airports in the US and Europe, based on specific flight needs. "This website is just one way we seek continued methods to serve the dynamic arena of business aviation and the market segment of fractional ownership, which has been a profitable and growing niche for us, both in our fuelling business and for our Mercury Air Centers," said Joseph A Czyzyk, ceo of Mercury.
