I inquired about LH here:

Basically I am looking at two options now:
IAD-FRA-BOM on LH (I think it is a 17 hour journey total) arrive at 01:30 AM in BOM, which sucks. $1400 + 70k miles and fly C class FRA-BOM.
The other option is IAD-FRA/DUS-DXB-BOM (or other Indian gateway) on EK (Emirates). $2100 total with C class on Emirates.
One issue is the layover in DXB. This, however, does give me the option of avoiding BOM. How much better is it to use a different Indian gateway?
I.e. Madras, Cochin or Hyderabad, although Jet Airways only flies non-stop from BOM and Bangalore to Goa. Arrgghh...... Maybe there are other acceptable Indian airlines.......?
