Janice D. Diamond purchases a ticket for DL domestic flight, under a codeshare partner (i.e. AeroMexico, KLM, Airfrance). Would Janice Diamond be on the UG list in accordance to her status on skymiles? What about John D. Silver in the same scenario (John Silver is naturally delta FO/skyteam elite, and not elite+ pax). I am asking it because we noticed that in several cases KLM website provided us with lower pricing for the same delta operating flights (US domestic) than delta.com, especially when making it tatl on the same trip. It is a difference of about $30-40 per ticket, but if we need (and we do need)- to book about 8 of those in a set, two or three times during the summer, it begins to add up.
