Wait...you left out "Admirals's Club", and in older era, flight engineer's, and navigator's And how about rudder's?Cruises are a modern thing and are nothing like the time when people crossed oceans as a form of point to point transportation. Modern cruises did not exist at the time when aviation and navigation diverged.
Here's some examples of the nautical roots of aviation:
- Airplanes were called "ships" and some airlines and/or maintenance crews still do (dispatching will use the tail (registration) number, maintenance will use the fleet number, aka ship number, which sometimes matches the tail number, but due to mergers mixing fleets, they may not match).
- Copilot's position is called First Officer
- Flight deck crew wear epaulettes and hats with clear nautical roots
- Commercial aircraft have their main boarding doors on the left (port) side as did ocean liners
- Left and right are called port and starboard
- Vertical walls are called bulkheads
- The place where passengers sit is called a cabin
- Cockpit is called a flight deck
- Various uses of the word "flagship"
- The place where the food is stored, and where the flight attendants prepare meals is called the galley.
- Lead flight attendant/flight attendant in charge is called the purser
- Flight attendants were formerly called stewards and stewardesses (which has fallen out of fashion).
Seriously, I get the point...but even on "Crossing's"....it was and is customary to tip your cabin steward, deck steward, dining room waiter, and just about every other person on the ship that directly provides a personal service for you. Cruise lines now add a standardized service charge to your fair, based upon the length of your cruise, with a higher per diem for those in suites. As mentioned earlier, you can adjust this amount at the end of your cruise, as well as tip additional amounts for exceptional service to an individual crew member.
I don't believe airline flight attendants receive gratuities. Only exception, may be on charter's, like when carrying pro sports teams. Not even sure about that...
