I would like to fly as many sectors as possible before first disappears. I am very happy to have a broad range of experiences and part of the interest will be comparing products on different airlines and aircraft.
It is interesting that there appears to be little up to date information on who stills flies with a first cabin or the routes.
OW still offers RTW in first so there must be some demand but I am really struggling to work out an itinerary that has many first flights.
