Well the OP is out of luck when flying Delta

. Last month they still served the Champagne Gardet Premier Cru;
A really gorgeous, balanced, elegant Champagne with vibrant sweet apple and red fruit notes in the nose and palate. Beautifully integrated and subtle, with a toasty-biscuity finish.
That one has been replaced this month in the summer menu (at least for AMS) with Lanson Black Label Brut Champagne;
A classic French Champagne, yeasty, toasty, baked apple.
