Hi everyone -
I'm a long-time lurker, but this is my first time posting. I've recently been assigned a project at work that will require me to travel internationally. After reading this message board for a while now, I know there are better ways (e.g., better seats, dining options, airport lounges, etc.) to get overseas. While I'm plenty skilled in domestic travel, the same cannot be said for international travel. I'm hoping a few of you could take the time to offer your advice with the TATL portion of my flight.

Being based in CLE, I'm going to have to take a regional jet to ORD, EWR, or IAD. I'll also have a short-haul flight within Europe with which I'm not concerned.

For the TATL portion of my flight, I have several options between UA and LH, all overnights in Z:

Option 1:
EWR - FRA, LH 744
Option 2:
EWR - MUC, UA 764
Option 3:
EWR - ZRH, UA 763
Option 4:
ORD - FRA, LH 748
Option 5:
IAD - MUC, UA 764
Option 6:
IAD - FRA, UA 772

Thanks,
BasedinCLE
