US Airways established minimum ticket prices in an effort to offset fuel costs

. "For example, for flights less than 500 miles, the airline is no longer offering non-sale one-way fares that are less than $69," according to a US Airways statement. "Similar adjustments have also been made for longer haul flights." JPMorgan Securities analyst Jamie Baker welcomed the move. "In fact, with jet kero at $3.50/gallon, we would suggest that no one-way fare below $99 ever be allowed to exist--including sales," he wrote in a research note, "though we realize this would eliminate a significant portion of Southwest's overall fare spectrum. And therein lies the problem."
