Through check-in did not work for me flying 9Wt NAG-BOM, and then by NW BOM to MSP. Jet airways staff just could not access the NW data base. The biggest problem as a result was that I had to lug my own luggage from BOM domestic to the international terminal to connect to NW. With the constant over booking that takes place in India, I was very worried until I got my boarding pass!

Next week I am flying NW MSP-EWR and then connecting on to 9W. I doubt very much if NW can do a through check in for me at MSP. I will know on Tuesday
