I was booked on BOS-ZRH next week (MAR24) and the plane was changed to old 332 on wednesday&thursday.

I called Swiss trying to reroute, they referred me to my travel agency, and said they cannot do anything themselves.
Swiss confirmed that they see J class open on alternative flights via JFK.
However my genial travel agency does not see J class open, nor does matrix.

There is difference in availability on swiss.com versus what you see in GDS...

Now I have to wait for a solution from travel agency, and if nothing works, I guess I will burn 2 evouchers to get to first class (O9 available)
