Slightly OT, but:

I am CP with a pair of certs and am looking at a fall trip PHL-PRG (via either FRA or MUC) for 4 pax (1CP and 3 dirt) using a mix of paid with certs and DM award.

I'm looking at the option of US envoy, LH first and LH business. While I have flown US J, I have not flown LH on the overwater portion. I know that US wants too many DM for envoy and they cannot be used for LH first but can be used for business.

How would you compare US J to LH first and LH business? Thanks.
