What a great topic this is, I don't check in here too often so this string almost got by me. I think it should be perpetual.

I don't have enough time right now to express my individual frustrations regarding the past six months of travel on AF as a DL passenger (I could write all night), I will however paste part of an email I recently sent to a friend who made a trip with me through CDG. Surprise, surprise, it relates to a lost bag (expletive altered):

Air France sucks, your problem is not that they can't find it, but that they still haven't taken the time to look for it - despite what they may be telling you. It's sitting in a big pile of bags in CDG and at some point the lazy f***s who "work" there will put out their cigarettes and send it to you.

I've had this happen to me at CDG twice in the past six months - the only two times I checked a bag through there. According to Delta, however, whatever carrier delivers you to your final destination on the same ticket you lost your bag on becomes equally responsible for its return - in other words, if your return to SFO is on the same ticket as the CMN-AMS flights then DELTA becomes equally responsible for the return of your bag. So, if this is the case (and even if it isn't) you should call Delta lost baggage service and tell them "the baggage people in AMS told me I should call you when I got home". If you do this right, Delta will then send a cable to Air France asking where the bag is and Air France will then for the first time actually look for and find your bag. It is important to note that AF will not inform you or Delta that they have found the bag, but it will show up at your work a few days later with all the original tags as well as your ID still firmly affixed. Let me know how things proceed.
