Just looked up
Etihad J for our dates for the multi city it is $20000 for 2
Looked at just turn to Paris in J $11770
Finnair in J $13577 for multi city return pretty much the same.
Vietnam Air can't fly into Milan but return to and from Paris $9417
These are all for my dates give or take a day or 2 i picked the cheapest.
I could not afford any of these flights.
I got my Y+ for $6900 for 2 people. Yes I know it is not business but its the best deal that we could get for a more comfortable flight than economy at a peak time. We flew to NYC last year in Business with Qantas and Cathay so I know the difference.
But we can spend the extra dollars on our trip.
