JetBlue Airways Corp. /zigman2/quotes/207639051/composite JBLU -2.23% reported Tuesday a narrower-than-expected second-quarter loss and revenue that rose seven-fold from a year ago to beat forecasts as the air carrier saw further month-on-month improvement in travel. The company swung to net income of $64 million, or 20 cents a share, from a loss of $320 million, or $1.18 a share, in the year-ago period. Excluding nonrecurring items, the adjusted per-share loss of 65 cents beat the FactSet loss consensus of 74 cents.

Load factor improved to 79.2% from 33.8%, topping the FactSet consensus of 75.6%, as traffic increased 1,223.7% to 10.80 billion revenue passenger miles and capacity grew 465.6% to 13.65 billion available seat miles. "In the second quarter, we saw strong signs that consumer confidence and travel demand is returning, with second quarter revenue doubling compared to the first quarter driven by pent-up demand," said Chief Executive Robin Hayes.
