Delta reports July financial and operating performance

Consolidated PRASM (passenger revenue per available seat-mile) for July was down 7 percent compared to the same timeframe a year ago, according to Delta's press release. The airline said the decline is due to close-in domestic yield weakness - or pricing on business travel tickets purchased close to the time of travel - the ongoing supply-demand imbalance in the trans-Atlantic, and headwinds from the company's Yen hedge positions.

Mainline completion factor - the percentage of flights that were not canceled - came in at 99.7 percent for the month, with preliminary data showing 81.6 percent of those flights arriving on time in July.
