I noticed it was no longer stated on the top right of my statement when it changed to Bonvoy so I thought that it would be gone soon.
So I checked online on Chase and it is indeed still written there as a benefit. And when I received my new card it was also written on the paperwork that was enclosed so it seems it should be around a little longer.
Except for the nights we are losing out as we receive less points per purchases than the newer version.
