I recently traveled roundtrip from San Diego to Prague via Detroit, Amsterdam (outward bound) and Paris (return). I was happy to find a reasonable ticket on orbitz.com and even happier that the flight was with Northwest and Czech Air as my Onepass miles program is with Continental who is in the Skyteam Alliance with both of these airlines. However, upon my return to the States I found out that the ticket type (which was a "V" class ticket only allowed me to collect 50% of my Continental Elite miles and no points. I called Continental and they confirmed that when you travel on a "discount" ticket with an alliance airline (my round trip was $900) you are only eligible for half of your elite miles. I just wanted to let others know in case you were banking on your miles to allow you to keep your gold/silver/platinum elite card.
