Carnival Corp.'s fourth quarter earnings topped expectations but its sales missed estimates. Its quarterly report card shows profit came in at 27 cents a share. Total sales came in at only $3.7 billion. While ticket prices and onboard spending rose, a heavy fuel derivative charge wiped out those gains. But, a bit of a brighter outlook is that the company provided full-year 2015 guidance that is in-line with expectations. Advanced bookings for 2015 are also off to a good start -- the cruise ship operator said Friday bookings for the first three quarters are ahead of last year even with tickets getting a bit more expensive.
