@Delta & @AeromexicoUSA Complimentary Upgrades and Upgrade Certificates

With all the recent schedule changes and the announcement that Delta Medallion members would receive both complimentary upgrades on Aeromexico flights as well as the ability to apply both types of Upgrade Certificates to flights operated by Aeromexico,  I logged in to see if any other flights had been affected.

Flight changes are not uncommon when booking months in advance, so I was not surprised when my return flight was now affected. Instead of flying directly to Atlanta, I now have to route through Mexico City.

With the change, and the new perks available (and two regional upgrade certificates coming up on expiration), I figured I would give Delta a call to see if I could apply them to the return. After a few minutes with the representative working on it, they confirmed that upgrade space was available if they changed my first leg (SJD-MEX) from a Delta ticketed flight to an Aeromexico ticketed flight. A few more minutes on hold and I had received my Aeromexico PNR and had selected seats on all the returns.

While there are still a few kinks to work out, the overall integration was very smooth!

Have any of you received complimentary upgrades on Delta partners or applied upgrade certificates on partners? Let me know!
