The cruise line recorded a total revenue of $1.3 billion in its second quarter and added it expects to generate record earnings for the full year 2017.

However, it added future foreign exchange rates and industry conditions may yet have an impact on its full year results.

NCL added despite the uncertainty, it expects to generate record earnings for the full year, surpassing previous guidance.

Adjusted earnings per share (EPS) is now expected to be in the range of $3.93 to $4.03, up $0.14 from previous guidance.

The increase in revenue was thanks to fewer dry dock days, meaning more capacity days,, the addition of Regent’s Seven Seas Explorer and Oceania Cruises’ Sirena to the fleet in 2016 and strong ticket prices as well as higher onboard and other revenues.

Norwegian Cruise Line Holdings president and chief executive Frank Del Rio said: “Positive consumer sentiment in North American and key international markets has resulted in a robust booking environment that continues to be one of the strongest in recent history which, combined with our targeted strategic revenue initiatives drove second quarter revenue and yield growth well above expectations.

“All three of our brands benefitted from strength across each of their respective markets and contributed to our second quarter earnings beat.”

Executive vice president and chief financial officer Wendy Beck added: “We are pleased to report strong booking trends across all markets for the back half of 2017 where pricing and occupancy are now up mid-single digits over prior year.”

“Strong booking volumes and firm pricing have benefitted our booked business for the next four quarters, contributing to the increase of our 2017 full year outlook and further solidifying our expectation for strong earnings growth.”
