This came in a 10-K filing today and flagged a change since the company's Dec. 20 business update.
Then, Carnival management said the Omicron variant was having some impact on near-term bookings but 'not any major impact on the second half of 2022 or 2023 bookings.'
Increase in pre-travel positive test results
In Thursday's filing, Carnival said: 'Since the beginning of our fiscal year, we have experienced an impact on bookings for our near-term sailings, including higher cancellations resulting from an increase in pre-travel positive test results and challenges in the availability of timely pre-travel tests.
'In addition, in the last few weeks we have seen a dampening of the booking activity for the second half of 2022 relative to 2019.'
Nearly all Q1 operations still on track
The filing continued: 'Despite the disruption caused by Omicron to the airlines and other forms of travel, we expect to be able to successfully operate over 96% of our previously disclosed available lower berth days in the first quarter of 2022.'
