NCL has always booked before on a cabin fare that included free one checked luggage. True with all US airlines, Lufthansa, Turkish Air and British Air. All those airlines we used before with BOGO. We did not have an issue with Delta on the front end of our cruise. We had a problem with LATAM at the end of the cruise and they claim that whoever booked the cruise did not specify the proper fare selection. As for the savings, i checked the airfares for routes we took and we could have saved some and not being appaled with an unbudgeted expense at the end of the cruise in a foreign country.
