a few weeks ago, my flight from CDG - JFK was cancelled.

I got a letter a week later in the mail apologizing for the cancellation and a comp of 25,000 skymiles. I didn't even ask for this.

Delta screwed up big time with my rescheduled flight. I wrote in to Delta and wound up getting a $250 voucher and 8,000 more skymiles.

Total comp = $250.00 and 32,000 miles. This was a coach class ticket.

Then, the Air France flight I was eventually put on to get back home was overbooked so I volunteered for a flight the next day. I got $400.00 from Air France for the bump.

Total overall comp = $650.00 and 32,000 skymiles.
