Hello fellow Flyertalk members!

I'm new to the Delta forum, because I mostly visit the Lufthansa forum, only. A friend of mine invited me to a flight FRA-JFK on Delta, so I searched the forums for a comparison of these two airlines. But unfortunately I didn't found any thread in this forum.

We are either going to fly in coach or in C class. Can anyone compare those two airlines regarding their planes and classes? Should I maybe better stay with LH or is this trip worth it?

Is there any status match program at Delta?

Thanks and best regards!
