J seats on DL coded, KLM flight
Infrequent flyer but fly Business cabin internationally. Have 3 seats assigned on Delta.com for DL9391 AMS-MSP on 12/26/2017, but when I look on KLM website, those seats are available. Not worried about the short KLM flights in Europe, but would really like to have seats together for the longer flight back to the US. Is there something I need to do to ensure we have the seats Delta says/thinks we have?
