No my ticket is an old DEL-MUC-MSY-MUC-BOM trip I had booked in July 2019 and couldn't complete due to the pandemic. The Lufthansa ticket ends in BOM. I had bought a AI ticket from BOM to CCU to take advantage of the 30 KG allowance and *G benefits.

I now cancelled the AI ticket and will buy a 6E ticket. I can pull up the AI option via LKO and DEL if I book a multicity trip. But AI (and to some extent 6E) will not sell me a ticket BOM-CCU with a transit, it patches two segments together into a PNR. Which explains why AI couldn't swap the single segment coupon and reissue the outbound in two segments.
