Costa Cruise or Costa 'a lot' as indicated on the wed.
We booked the cruise via Thomas Cook who we feel manipulated the fact that Costa Cruise who will allow you to book a cruise & flight even though 'no' flights were available & then contact you three days later to say 'sorry' we don't have any flight - so Thomas Cook then offer to construct a package for you, which you end up paying £400 plus more for!
We flew with both KLM & Air France.
