Hi, I am looking at using Delta miles for a trip to Italy. I have a couple of questions. I have no status on Delta.

1. Has Delta suspended change fees for award travel? If not what are the change fees. The only thing I can find is the $150 redeposit fees and no fees within 24 hour of booking.
2. Is Delta good at accommodating schedule changes? I am looking AF from SEA to CDG connecting to AF CDG to VCE. According to Flight Aware, the last time SEA to CDG operated was a year ago. If SEA to CDG is changed, would Delta re-accommodate us either on KLM or on Delta?

many thanks.
