I picked up two of these cards last year and earned 186K miles.
I just booked 5 RT flights MSP to MBJ for 175K miles. Those tickets price out on google flights for $923/each. These are nice nonstop Delta flights. The cheapest flight with stops on the days of my trip would have been $876. So 90K gets me over a $2K value.
Also, one nice benefit of using VA for Delta flights is I can cancel for only a $50 fee, whereas Delta has no cancel option. (One of us may not be able to go, so this is a cheap way to lock in the flight.)
They also seemed to have messed up the trip in some way to my benefit and only took out 140K miles. I have all 5 tickets and have selected seats for them on Delta. I think VA possibly did a manual adjustment because I also had a lap child, so maybe they thought they were charging miles for that and then took off the 35K? I don't know. Fees were also about $100 less than they would have been on Delta as well. So I don't know why but I came out really well on this trip.
I live in MSP so Delta flights often come out to be much more valuable to me than AA or United. I have been able to use great availability on non-stop Mexican trips as well. I should note that AirFrance can book Delta trips as well and they take 5K RT less miles to Mexico/Carib, but I find their fees are also $50 more, so it is a bit of a wash.
