MIAMI — Carnival Corporation & plc saw net income more than double in the second quarter of 2015 to US$222 million including unrealized gains on fuel derivatives of $34 million and $7 million of restructuring expenses.

For the second quarter of 2014, net income was $98 million. Revenues for the second quarter of 2015 were $3.6 billion, in line with the prior year.

Carnival Corporation & plc President and CEO Arnold Donald noted “We more than doubled our second quarter earnings versus the comparable period a year ago and significantly exceeded our quarterly earnings guidance. Our initiatives to create demand and leverage our scale benefited both cruise ticket prices and onboard revenues contributing to 5% revenue yield improvement (constant currency) this quarter. While all of our North American brands enjoyed strong revenue yield improvement, our Carnival Cruise Line brand performed particularly well again this quarter”.

Fuel prices declined 37% to $411 per metric ton for 2Q 2015 from $657 per metric ton in 2Q 2014 but were higher than March guidance of $402 per metric ton.

During the last 13 weeks, fleetwide booking volumes for the next three quarters were running well ahead of last year at slightly lower prices due to transactional currency impacts. At this time, cumulative advance bookings for the next three quarters are well ahead of the prior year at slightly lower prices again due to transactional currency impacts.

Donald noted “Current strength in booking volumes clearly demonstrates strong consumer demand for our brands, leaving less inventory remaining for sale and building confidence in achieving significant revenue yield improvement this year. We are stepping up our marketing investment for the remainder of the year to further solidify our base of business for 2016 and drive continued yield improvement as we progress on our path toward double digit return on invested capital.”
