Ummm so loaded onto a jet with 300+ others in Y class without enough leg room to be able to move, some strangers shoulder on each side of you touching yours and having to pay $6.50 for a 300ml bottle of water is somehow a vastly superior experience to having a luxury cabin with a great night's sleep, someone making your bed, cleaning your room and bringing you breakfast in bed or on your private balcony, and sophisticated 5 course silver service meals???
Don't get me wrong I love flying and have well over 1000 flights under my belt to over 70 countries but I have also done a dozen cruises.
It's horses for courses.
Sometimes a flight itinerary visit to several cities in a short space of time is nothing short of pure hell with delayed flights/ tight connections, little sleep, and packing/unpacking and waiting around airports and panicking over late taxis overweight luggage etc, etc etc etc etc.
A tour of the Baltics by air in two weeks would be a nightmare. The cruise was absolute magic a new city out the window every morning as I finished breakfast and went for my shower. I never take ship excursions and organise a private driver to be waiting for me at each port if required.
Whereas a cruise around South America only seeing an occasional insignificant port with heaps of sea days in between would drive me insane.
