Has anybody tried to price same itinerary on CO.com vs. NWA.com? I was looking to book a trip CRP- SIN this morning and on CO it priced at $3400 for an H fare. Same flights on NWA priced at $2400 in Y for NWA coded flights on CO metal (CO 2258, CO7, NWA 6 and return). I thought that was interesting. Plus I do not think it will qualify for low fare guarantee since on NWA.com the flights are coded as NW flights. Oh well. I booked on NWW and used some of my WP miles to upgrade.
