I too am very happy for the new arrangement as I fly frequently to Europe and then on to the States. But we must remember that when Swiss had a codeshare with AA including from TLV to JFK via ZRH the prices for the AA codeshare tickets were outrageously high compared to flying on the same flight on a Swiss ticket. I am sure that it is the same on other airlines and routes throughout the world
So the question basically is how much extra are we willing to pay for miles, EQP, EQM etc above what we would pay to fly on the original metal's flight number?

Of course Happy Chanukah to all !!
