," according to J.P. Morgan Securities analyst Jamie Baker. He said the price hike impacted first-class and full-fare economy tickets, and increased to $699 the carrier's one-way domestic fare cap. "Delta’s initiative was partially matched by American Airlines, fully matched by US Airways and expanded somewhat by United to include capacity-controlled walk-up fares," Baker added.
